Look out Technorati and Google Blog Search. BlogCatalog is gaining on you.

BlogCatalog.com has just announced the launch of a new “total aggregation search engine” that helps you find anything on their blog directory and social network as well as on more than 20 other social media websites.

For instance, you can select “All Results” above the search box and search for blog herald to get a section-by-section list of BlogCatalog members, BlogCatalog discussions, other slice-and-dice results from BlogCatalog, and (perhaps most interestingly) results from StumbleUpon, Delicious, Twitter and many other popular social bookmarking or social networking sites. read more

Promising to help you ‘find better blogs’ is Blogged.com. The directory site has just launched some new features and improvements. Most notably, they do a better job of highlighting interesting blogs over several niches. The goal appears to aggregate news and information that is well-written, though not necessarily accessible through mainstream media.

Among some of the content currently on the homepage:

Everything I Learned About Personal Finance I Learned From WALL-E

White Collar Steroids

5 Terrible Life Lessons Hollywood Loves to Teach You

Sure, you could visit Digg or any other wisdom of crowds Website, but the new Blogged design is highly readable with content being hand-picked by a team of editors.
