One of the more difficult aspects of reading websites with an active reader or user community is separating the useful comments from, well, the cruft. Oftentimes the really interesting an useful content can get buried or lost under than a ton of “me too” replies. This is where the new comment plugin system, SezWho comes into play.

SezWho, as their site states, “is a distributed context, rating and reputation service for blogs, forums, wikis and other social sites.” Essentially it’s plugin that grants both visitors and web site owners to rate the content and value of comments. If a website uses SezWho, it becomes much, much easier to parse content based on its rating and overall usefulness. Download Squad is having a BLAST at SXSWi 2008 and this day we had a chance to sit down with SezWho’s founder and CEO Jitendra Gupta. Jitendra showed us the various features of SezWho, and we have to state, we’re impressed.

The most interesting aspect of SezWho, to us, is that user comments can be linked across blogs. So if you leave a comment at one site with SezWho, other readers can view your other comments to other SezWho sites. This makes it simple to find out how helpful/informative/useful a comment actually is and to build your own reputation and rating system across a number of blogs. Ratings are based not just on user votes, but also how often you contribute and the context of the comment itself. So if you post a comment on a political website, that is not going to adversely (or positively, for that matter) affect your overall user rating if you comment on a sports website. For commenters, people can view your profile, find out other sites you’ve contributed to and find your own website.

For website owners, you can use SezWho not only to engage your community and to build interaction, but if you want, you can even highlight your most popular and highest rated commenters. You can also track how many referral links various comments or commenters bring in.

plugin on your comment page will soon be fully customizable via CSS and various themes and styles are coming in the future.

If you’ve your own blog and are looking for a good way to interact with your readers, consider giving SezWho a try. For readers and commenters, its a great way to build reputation across various sites and also view the ideal content immediately.
