6) How does it differ from web 3.0?

This links into the notion of web 3.0 as semantic web is seen by some as part of this new 'web' . Wed 3.0 attempts to blur the boundaries between human-computer interaction by attempting to make computers 'think' more like humans. For example if you wanted to go our for a meal and see a film currently you would need to search online for film times/locations, choose your type of restaurant, location, opening times and then bring all of these searches together to make sure everything worked ( e.g. your film doesn't start half way through your food ). Web 3.0 aims to allow users to input more complex 'human' search information. "I would like to have a Chinese meal and then see a film. Which places are best?" Web 3.0 would then 'decode' your search, perform the necessary searches for restaurants etc. and collate the possible options for you (the inclusion of information from 'review' sites could also be used to provide you with peoples opinions of your options). Some even claim that web 3.0 could begin to 'learn' your preferences and make informed recommendations. The best way to imagine this system would be to look at the current trend for 'price comparison websites' These take a lot of data from different companies and turn this into usable information for the user. Web 3.0 proposes this kind of usability but on a dramatically bigger scale.
