HotJobs starts crawling other job postings, Jobster buys WorkZoo

Charlene's got a good response to the Yahoo/HotJobs announcement that they've started crawling other sites and including those job postings in their listings. I think her take is dead-on, and in fact wrote something similar last week. Here's her money quote (IMO):

The result: Look for the emergence of what I call "social classifieds", where the ability to connect people to each other will be the hallmark of success. In a world where listings are a commodity and easily crawled, the true differentiation will be the quality of the experience. It is for this reason that Jobster's model will ring true, and why Yahoo! 360 and MSN Spaces will be core to the success of their respective classified strategies. Google may have the best technology around, but it's Achilles’ heel will be its lack of a robust social network.

Interesting to note:

• Yahoo has HotJobs and Yahoo 360 and has already demonstrated social search capabilities
• Monster has Monster.com and Tickle Social Networking
• SimplyHired has a partnership with LinkedIn
• Jobster acquired WorkZoo

The first round of Social Networking was around personals. The next seems to be a jobs applicatoin. Can some implementation of Mark Pincus' vision at Tribe.net be far behind?
