Feel good community site craigslist announced today that eBay has bought 25% of the company. Craigslist founder Craig Newmark has the details at his weblog. Apparently, he gave equity in the company to someone who later left the company, and that person wanted to sell out, and wound up with eBay as a buyer. After the eBay folks verified that buying the shares would be OK with the craigslist folks, the transaction was completed.
