Version 2.0 of SezWho, a blogging plugin that tracks commenter reputations, has been launched with wider support for blogging platforms and forums. SezWho can now be used on Blogger, Drupal, WordPress 2.5, and phpBB.

SezWho is also releasing a developer toolkit with APIs that 3rd party developers can use to make the software work on even more discussion platforms. Other new features include RSS feeds for various “conversation streams”, OpenID support for logins, cross-platform avatars, greater CSS flexibility, and support for anonymous ratings.

SezWho raised $1M in funding last October. Competitors include Disqus, JS-Kit, and Intense Debate.
