These are the sites that cover the Web 2.0 revolution.

AppScout
This might be viewed as self-serving, but our AppScout blog is a great place to find software tips and tricks, cool or useful Web sites and apps, and the latest news from the world of Web technology. The blog is written mainly by PC Mag editors and analysts, and we give readers exclusive access to our regular vendor meetings, trade shows, and interviews.

Download Squad
Download Squad is basically Engadget for software and Web apps, and it's owned by the same company, Weblogs Inc. The blog traffics in rumors and news announcements, posts frequently, and has fun content like "Today's Time Waster"-ways for bored cubicle-dwellers to entertain themselves online.

eHub
We're still trying to figure out how she does it, but somehow Emily Chang manages to get wind of every Web 2.0 app long before the rest of the blogging world does. Her synopses are short and sweet, which is just fine, given the frequency with which she updates her page. eHub has been doing a bit of branching out recently, too, adding interviews, job listings, news, and events.

MakeUseOf.com
If you're searching for in-depth, hands-on reviews of the latest Web apps, keep looking. MakeUseOf.com's real strength lies in its quick but surprisingly comprehensive roundups of apps and sites in a given space. If you're looking to discover the best iPhone apps, Firefox extensions, or accounting sites, MakeUseOf can point you in the right direction.

Mashable
Sick of hearing and reading about the social-networking revolution? Then steer clear of Mashable, a blog devoted to covering MySpace, Facebook, and their ilk. Mashable reports on the exploding world of social-networking apps and features. It's a top-notch news resource for Web 2.0 developers and even MySpace users who want to pimp their page with the latest plug-ins.
