The question of how to define Web 2.0 is a common one, and this weekend I was able to listen to a conversation that covered all the based quite well.  The folks at Jupiter Research have been podcasting for some time now and their most recent release was a conversation between company VP and Research Director Michael Gartenberg, analyst Barry Parr and facilitated by Senior VP of Research David Schatsky. 

Titled "Web 2.0: What Does it Mean for Business?" I found this to be one of the most easy to understand and thorough discussions on the topic available.  It's 30 minutes long and well worth a listen.   The discussion covers the history of the technologies involved, the role of user genertated content and much more.

 I know that some people think the term is meaningless, but I think this podcast is one more bit of evidence that's not true.  The software in use and the societal impacts are real.  I've got my own definition on my site, and I include links to the most up to date search results for other people defining Web 2.0 as well.  This Jupiter discussion is really impressive, though.
