I've never heard the term 'web 2.0' uttered by *anybody* who didn't work in marketing. It's meaningless.
For something to succeed it has to either do something new that people want (like bitcoin) or do something better than the existing methods (like twitter). User friendliness doesn't have a lot to do with it, really.. people will cope with a lot of crap when the alternative is worse. That *will* come to bitcoin, btw. Someone will write a friendly client.. there's no company here to direct it and absolutely no contradiction with this forum concentrating on the technical details whilst someone currently unknown goes off and makes the killer UI.
You really have no idea what your talking about. You are arguing with an industry expert here bud.
"The term Web 2.0 is associated with web applications that facilitate participatory information sharing, interoperability, user-centered design,[1] and collaboration on the World Wide Web. A Web 2.0 site allows users to interact and collaborate with each other in a social media dialogue as creators (prosumers) of user-generated content in a virtual community, in contrast to websites where users (consumers) are limited to the passive viewing of content that was created for them. Examples of Web 2.0 include social networking sites, blogs, wikis, video sharing sites, hosted services, web applications, mashups and folksonomies."
http://en.wikipedia.org/wiki/Web_2.0When I use the word web2.0, I mean EXACTLY what it means on wiki.. Forums by nature are not web2.0, unless you do many mods, and even then, they stink, because they are not properly connected, designed, and/or tested.
