Michael Arrington’s Tech Companies to Watch in 2007

TechCrunch’s infamous Michael Arrington has listed the “Web 2.0″ companies he couldn’t live without in 2007, but we may as well call it “the top tech companies to watch in 2007″.

It’s a list most marketers should consider reviewing. While it has some tech companies that don’t quite cross into marketing, Arrington’s list is full of social media and search companies, including Ask City, BlueDot, Digg, Flickr, YouTube and more.
