For those of you that don’t know, Mike Arrington is the impresario behind TechCrunch and the godfather of Web 2.0 punditry. The following is an excerpt of his annual listing of Web 2.0 must-visits.

1. 800-Free-411
800-Free-411 was first added to the list last year. Use it to make free directory assistance calls and avoid per call charges of up to $3.50 that cell phone carriers charge. They have taken more than 6% of the market for directory service calls in the U.S. over the last two years. Google, Microsoft, AT&T and others have entered the market, but Jingle Networks, the company offering the product, has a patent on the idea of pairing advertising with free directory service. Here’s a tip: add “FREE411USA” as a Skype contact and do lookups that way, too.
2. Amazon MP3 Store
Amazon’s new music store is just about perfect. With the addition of Warner Music they’ve got 3 million DRM-free songs at prices lower than Apple’s iTunes store (which has only 2 million DRM-free songs). It’s not as cheap as AllOfMP3 was, but at least it’s guilt-free and legal. Plus, it will hopefully drive Apple to improve iTunes (offering no-DRM only search would be a good start).
