I was reading a column by Louis Gray that Technorati is now making a comeback and focused on quality.  Technorati was/is a blog search and rating system that had a spam, quality, and service uptime issue.  Nearly on the brink of death, the site started a turn-around in 2007 and has made a comeback in October 2009 with a "beta" logo.  I logged in to my old account and tried to update my profile - major issues with a simple process - I'd say their quality still has a long way to go.  I've updated my blog with Zingodia Systems and need to place this code - UEUY56N58ZV3 - for it to verify I'm a writer of this blog.  So we'll see what the "new" Technorati is about over the next 30 days and I'll keep updating as to its use and effectiveness.
