Hi Alon, thanks for the answer. I'm looking for Israeli Web 2.0 companies in the vaguest of terms - where the users provide the content and collaborate. I'm doing a series of posts about Israeli web 2.0 companies on a blog where I contribute. I'm also working on a piece for Israel21c.org about web 2.0 companies and figured that it would be interesting to get information about the topic via an Israeli company, hence the post here. 

I understand on a "philosophical level" that the term Web 2.0 is not well defined but the more companies that launch products, the more similarities we see in what drives the product. Thanks again.
