Today Entrecard announced a partnership with SezWho , a universal profile service for the social web designed to engage communities and enable content discovery.

SezWho allows you to set up a profile, and have your comments across blogs using SezWho aggregated. So if you offer an erudite comment on blog A, people who read it can click your profile and see posts from your own blog as well as your comments elsewhere in the blogosphere.

In combination with Entrecard, not only do you get the advantage of a ‘carry along’ profile, but you can earn EC credits for your posts too.

However, we wouldn’t want people running around and writing “nice post” on every blog they see, trying to game the system and earn credits. So the community will be responsible for rating comments, and rating them truthfully. Depending on how well your comments get rated, and who rates them, your comments will earn you a sliding reward ranging from 1 to 10 credits. If your comments get rated poorly, especially by a blog’s owner, you won’t earn a thing.

This rather brilliant move should help to significantly offset the Bounce Rate problem that Entrecard has had.

I’ve just installed the SezWho plugin, and will be watching my Google Analytics carefully to see if it does improve my bounce rate, which went from ~30% before Entrecard to ~75% after.
