What is the difference between web 2.0 and web 1.0?

web 2.0 is based more on server side technology that is php, ASP.NET, etc. It is how sites like youtube function because it can create dynamic pages on the fly. Also it represents a standard, 4 example the current trend of web designers love of curves rather than straight lines.

Web 2.0 is just some marketing term. It just means what id perceived as a second generation of web development/design. http://en.wikipedia.org/wiki/Web_2.0

Actually, there is no such thing as "web 2.0". It is a term that has been coined to emphesize the time when the web became more INTERACTIVE!

Community is basically interaction between members, between websites, and between the website admins and its members. In the old days, we had the BBS and then IRC and then forums. Now it's more of the same, but also extended in one crucial way: we are happy to share without claiming ownership. The best example is Wikipedia: no one claims copyright control over it, and so we are breaking the traditional authorship rights. When we contribute to Wikipedia, anyone can read our contribution, anyone can copy it, anyone can edit, and dang it, anyone can delete it. This is very new. The other new thing is voting. Now we have popularity contests of our contributions. Our forums have reps, delicious has the popular lists, and of course digg is the ultimate voting system. If you think hard, you can also convince yourself, Google's PageRank is essentially an algorithm that measures social popularity (link = vote). 2. Technology. Here we talk about XML, APIs, new content management systems like blogs and wikis, and if you're that inclined, sure, AJAX. The new technologies support the formation of communities and the interactions I explained above. XML gives us RSS and AJAX. APIs are a more general term that gives us mashups, and arguably, everything else. Basically, it's the use of standard technologies everyone agrees on. This, IMHO, is the biggest "technological" breakthrough: actually agreeing on a technical standard!!! ... Web 1.9 You stumble upon Desktop Tower Defense one lunchtime, and are surprised when you look up from the screen with tired, gummy eyes to notice that it has suddenly become tomorrow. But at least you have got your world ranking up to 912,417. Web 2.0 At last! You can get a fully fledged mail client in your browser. Now, wherever you are in the world, whatever time of day, without the need for your own PC, you are no more than a few minutes away from a screen that reads "Oops, something has gone wrong; we're sorry, try again in a few minutes".
