Technorati, the second most popular blog search engine next to Google Blog Search and 5th largest social media space, recently underwent a “web 2.0″ face-lift. Some changes were for the better, some for better business and some are a work in progress. A few cool new additions are Twittorati – a Twitter API, the Technorati Blog, and a few more Technorati properties.  However, it seems that for the time being, Technorati is a bit anti-social.

The Technorati profile, once a way for bloggers to connect with fellow bloggers and subscribe to blogs, has been crippled for a couple months. Currently, members cannot subscribe to blogs and blog reactions have been reserved for “authoritative” sources. Meanwhile, Blog Catalog offers a few features Technorati does not – it is not only a blog directory and blog search engine, but a social network, community, blog activity stream and blog subscription service.

I certainly hope that Technorati finishes their updates soon, because as better subscription and blog community options remain available, Technorati may lose the user-loyalty that their “Faves” feature afforded them. I trust there is a larger vision at stake with these massive changes, and look forward to a socially optimized Technorati in the near future.
