New SezWho functionality includes four new profile templates, including support for popular threaded discussion formats. More importantly for site owners, SezWho now offers support for local CSS and JavaScript. Other new features include Thumbs Up and Thumbs Down ratings for posts, configurable pop-ups, improved support for filtering, support for multiple WordPress installations in a single database, and easier upgrading.

SezWho has also announced a new partnership with Instablogs, that will see SezWho bring reputation management and universal profiles and content to Instablog readers. Instablogs’ readers can now rate posts and user-generated content on Instablogs and across other SezWho-enabled social media sites, including blogs, discussion forums, and bulletin boards.

The new features will be a welcome addition to SezWho users, and help the service define itself in a competitive space. The deal with Instablogs sees SezWho now powering a number of leading blog networks, including Creative Webloging.

Entrecard’s blog ad network has added SezWho as a way to reward bloggers who participate on the site. Bloggers whose SezWho comments receive high ratings through SezWho will receive Entrecard credits to be spent on advertisements within the 14,000 strong Entrecard advertising network.

Blog network Creative Weblogging will offer SezWho reputation-driven user profiles across its network, and Izea will use SezWho to power its SocialSpark Solution Center.

The commenting 2.0 space has turned into a numbers race as the various players look to increase their presence. These three deals give SezWho a serious leg up against rivals including Intense Debate and Disqus. There is room for multiple players in the space, but the service with more eyeballs will ultimately come out on top, and perhaps go on to become the Google of the 2.0 commenting space. Expect more deals like these in the coming months.
