Your site says nothing of how the system actually works. How does it identify individuals across sites? How is reputation calculated?

If you did this the obvious way (HN or Reddit-style karma keyed to email addresses), you're going to run into a couple problems. First: if your startup takes off, users with a grudge will have a way to hurt another user's reputation across a large chunk of the Internet. This is obviously an issue with existing reputation systems, but there the damage is contained.

Second: trolls are accustomed to creating new addresses for each campaign on a troll-hostile site. The users you really need to worry about wouldn't have negative karma, they'd have a blank slate.

I'm one of the other participants. It is true that the site does not have much content at all, we're just throwing something out there to get feedback from potential customers as quickly as possible. The idea is to let implementors/sites choose whether they will keep the reputation-system scoped to their site only, to a collection of sites (usually in the same space), or globally.

Our algorithm for calculationg reputation is an improved upon version of the attack-resiliant trust metrics of http://advogato.org.
