If you are interested in exploring the best of Web 2.0, a good place to start is the recently announced SEOmoz’s Web 2.0 Awards. The awards honor the best Web 2.0 sites in 37 categories, from blog guides and bookmarking to Web development and wikis. Each category lists three winners and several honorable mentions, adding up to several hundred sites to explore. Whether you’re already a Web 2.0 aficionado or merely curious to find out what it is all about, you’re likely to find something of interest among the sites here.
