Om Malik reports that Yahoo is buying scheduling/meetup tool Upcoming.org.
This is interesting for a couple of reasons:

• Yahoo is clearly chasing Google to build the base tool set/platform for a consumer-driven Web 2.0
• It sends (yet another) signal to start-up entrepenurs in the tool set/social media space that acquisition is the most likely outcome for a viable product with a decent user base and cool apps
• There's a (new) rush to acquire and integrate these new tools--and take them off the market
• The bubble--at least in Silicon Valley--is truly back(in other words, this convinced me)
• We're moving into a digital divide between the application makers--Yahoo, Google, eBay--for example--and the media and information companies--who have the content, but lack the means to both build and integrate--that's the reason they acquire, but can they do as much with the compaies they snap up?
