Below is a mishmash of thoughts that crossed my mind while at the Web 2.0 conference last week.

• If you attended the conference you'd have gotten the impression that "web 2.0" isn't about technology or about social effects, it is about money. Specifically "web 2.0" is a meme that tries to describe the characteristics of the new generation of startups that have gained success either by IPOing (e.g. Google) or being bought by large companies (e.g. Flickr). The targets of this meme are VCs (to tell them what kinds of companies to invest in), startups (to tell them what kinds of companies to emulate) and big companies (to tell them what kinds of companies to buy). The fact that there multiple panelists were VCs is also very telling.

• Google is the new Microsoft. Several times during the conference, it was brought up that Google has replaced Microsoft as the company that Silicon Valley companies love to hate because it enters nascent markets and dominates them (e.g. there was visible negative reactions by some audience members to the announcement of Google Reader) 

• Microsoft isn't on anyone's radar in this audience except as an example of an aging dinosaur or the butt of some joke. This is consistent with the impressions I've seen at other conferences such as ETech and Gnomedex.

• Just like in the dotbomb days of 1999/2000, most "web 2.0" companies don't have a business model besides getting bought by a big company. The new crutch many of them lean on is Google AdSense when queried about how they plan to be profitable.

• Sun Microsystems is living on borrowed time. Their business strategy now seems to be one giant Hail Mary play.

• The folks at Yahoo! Inc totally get it. If I was at Google I'd probably spend as much time worrying about them as I do about Microsoft.

• Meebo reminds me a lot of the dotbomb days. It's basically an AJAX version of Trillian.  Building an AJAX version of Trillian is cool from a geeky perspective but I honestly don't see them lasting long except if they get bought by some bigger player like Google, Yahoo!, MSN or maybe even Trillian.
