I think one of the most interesting aspects of the article is the concerns over Zynga's dependency on facebook, especially with the recent unveiling of Google Plus. Could the demise of facebook be in the not too distant future? Probably not, but it is interesting to think about. I am really looking forward to seeing Zynga's S-1 which is rumored to come out after markets close tonight. I just don't see how these valuations can be justified, but that doesn't really matter to investors as long as they are seeing returns off of these IPOs (and they are). I am really fearing the tech industry might be building its own "ponzi scheme" with these valuations only to see another 1999 bust.
