Qassia is a backlink generating website. Adam Waldman had sent an invitation to me a couple of weeks ago... I just finally got around to checking it out.
The basic deal is that we write small posts (called intels) and for each one we get a backlink. The backlinks are not reciprocated, so they actually have a higher SEO value than reciprocated backlinks. There are also the benefits of belonging to yet another social network.
It is free to sign up and participate, and the site is still in beta, so apparently one needs an invitation to join up. Here is an invite (which is a link to my page...). Feel free to wander over and sign up if you think it is interesting. And for you point hounds, they have a points system, too...
