Technorati, the blog search engine, raised $7.5 million in third round investment this week. While the Technorati name has some cache among tech geeks, bloggers, and social media types (have you heard of it?), the site's not without problems. Big problems. Along with constantly battling off the Google monster and other competitors, the site has struggled with long, Twitter-like downtimes, and had a management shakeup last year, that resulted in dumping the CEO and laying off numerous employees.

While that doesn't paint the prettiest picture for an investor, bigwig VCs like Draper Fisher Jurvetson got in on this round. They either know something we don't, or as a Washington Post blogger speculates, "It looks like the backers are putting more money in, largely cause they have chips already in the pot."

Ouch.
