Many people call web 3.0 the semantic web as they are very similar. As by adding semantic web to web 2.0 then you are close to achieving web 3.0. Web 3.0 is a 'webservice' that will expose all information to the world.
Web 3.0 is alot more advanced than the semantic web and will eventually replace web 2.0. It will essentially be a web service in which the web will understand and be able to meet your requests. Web 3.0 will almost build up a memory and will store information entered by the human and when you search for things online it will offer choices that suit your taste.
There are many similarities between the semantic web and web 3.0 and so it was hard to fnd differences and on the web many websites have stated them as the same thing but i would say that web 3.0 is more advanced than the semnatic web and is more personalised than the semantic web. The semantic web is almost the stage before web 3.0 and will probably be achievable before we reach web 3.0. Web 3.0 also gives results personal to the user where as the semantic web gives all of the results possible even though both of them give information to the world.

What is the 'semantic web'?
The semantic web is an extension of the world wide web. Semantics of information make it possible to understand the request that the user has asked when trying to view web content instead of understanding just a few key words in a sentence the semantic web understands the whole sentence and will fit your needs.
The concept and idea was originaly composed by Tim Berners-Lee and is seen to be one of the vital components of web 3.0. By using tools such as OWLs and XML that are organised into stacks this helps to breakdown the sentence or phrase typed in by the human and finds out what it means.

Education and Culture
Is there a potential problem being stored up for people if 'education' is tailored to fit into their cultural and personal preferences?
I agree that there is a problem in the way that education is tailored to fit into people's cultural and personal preferences as if people only had their own preferences in a course of what to do then they would maybe not learn all they should do or schoose not to learn something as it is boring however relevant to the course. I feel if education is tailored it could become narrow minded and people should learn about other people's cultures and beliefs to be able to understand other peoples cultures as we live in a multi cultural society tounderstand other peoples culture is important. If this does happen then I feel it will increase divides in society in schools. Does this mean that you would have to have seperate schools for people who are in different cultures? Which would cause racism and segregation.

Digital Divide
What difference to all this might the 'digital divide' make? a) To socioeconomically related access issues within a society? b) To global access issues across countries and regions?
a) Especially in times like this with the credit crunch the digital divide is becoming bigger. As people with less income cannot afford and do not always have access to the latest technologies causing more of a divide as the people who have the latest technology have a different understanding and use a different type of language and terms than other people. Although a government programme has been set up in England to help get people with lower income access to the internet there are still many people without internet and in inpoverished places no access at all is avalaible. However with the vast improvements with technoogy and the ever growing reliance on the internet as more and more things are avaliable and reliant online then the gap is getting bigger and people are finding it harder and facing 'social exclusion'
By giving all children access to the internet they can use it to learn online however computers are expensive and not everyone can afford or access them.
b) This is a massive issue globally as although as although the digital divide can be closed impoverished countries. As rich countries have more access and the majority of people have access to the internet then it is making the divide bigger. 80% of the world have never heard a dial tone and in the poorest countries in Africa then the resources are not avaliable in the government to grant the people access to the internet or a televison. In England programmes have been set up in Notttigham, Liverpool, Suffolk, East London and Hull to try and get one laptop per home.
The UN have decided set a plan to eradicate poverty. In Latin America, Africa and Asia there have been plans to demolish the digital divide. By making it possible for people in third world countries to access the interent then elearning could be more accessible and people would be able to get an education meaning that people could get better jobs being the first step out of poverty.

How might Wenger's notion of practice communities to relate to Prensky's on education?
Prensky and Wenger both suggest in their theories that it is not only the management and techers of a business or school that can help the employees or students in the work area. Wenger states that members in a community of practice 'engage in a collective process of learning' and so together they learn without being taught and told what to do by people higher up in the hierachy. This is similar to the fact that Prensky's theory that students know more about new technology than their teachers and so teach themselves instead of having to rely on lecturers to teach them.
Both theorists believe in group learning. While Wenger believes that communities of practice is all about learning together with and helping each other out to get he best results. Prensky also believes in group work as he believes in the idea of online study groups where students can learn together online and work together to help students understand work set.
Prensky focusses more on the internet and how people use technology in education whereas Wenger believes that the learning process is not just based in education but in hobbies, the work place or in activities.

Threatening the digital native/immigrant culture.
The only person I can think of that threatens the notion of the digital native and immigrant culture is my Dad's best friend Dave. As he knows how to use a computer and uses new technology with ease daily and she is over 50. He always has the latest phone, camera and video camera. He seems to know alot more about the latest tyes of technology than me or anyone else my age.His job is to fix televisions, computers and cameras. He also works alot for repairing these types of media for John Lewis.
He has no 'accent' and I feel although his age would place him in Prensky's category of 'digital immigrant.' This term I feel is generalised as I do not feel just because you were born in an age of new media that you toally understand it all or are completely fluent in it. Media is always changing and improving and I am not familiar with alot of the latest phones and cameras and I wouldn't know how to use them. Alot of people are alot more familiar with modern technology than me and I am not one of those people who always has the latest up to date technology so maybe in some ways I would be seen as a digital immigrant myself. At the rate that technology is improving does this mean that the next generation will look at us as digital immigrants?

The youngest 'digital immigrant' I know.
The youngest digital innigrant I know is my friend Phil who is 21. He does not like computers at all and does not use a camera or invest in an up to date phone. As he doesn't use a computer he does not have an account on Facebook and doesn't have an email account. Instead he prefers contacting people by phone if he wants to talk to them and uses books and encyclopedias to find out answers to questions instead of using search engines like google. He also doesn't trust alot of websites on the internet and so uses more reliable resources like books and articles to use in his essays.
As he is only 21 he should be a digital native in terms of Prensky's theory. However I feel that it is sometimes seen as an assumption that people born in the new age of media will fully use and understand and rely on it. However this example and many other people have proven that this is not the case and although you are more likely to use technology but it does not mean that everyone born then is fluent in the language of new media.
