A TechMeme Clone For Stock News recently surfaced in the TechCrunch Forums. It’s an aggregator around public company stock news that has a suspiciously similar approach and look/feel as blog news aggregator TechMeme.

The site groups news items from major media (Reuters, WSJ, USAToday, etc.). Lots of stories = higher placement on the site. Newer stories are linked in the right sidebar. It updates every 15 minutes.

Like TechMeme, this will be a killer resource for people tracking breaking public company news.

The difficult part of building an aggregator like this is figuring out what stories are related and grouping them properly. TechMeme uses links between blogs. Since major news sites don’t link to each other, must be using keyword and semantic analysis.
