SETT is mine... Applied to YC almost a year ago, didn't get in, been hustlin' anyway.
Right now it's in private alpha, just a group of 20 trusted people running through it. By the end of this month, it will be running on my personal blog. I'll make a post on HN about it then.
Agreed, it's interesting but I have no way to gauge it. There's no obvious publication date so for all I know it's 5 years old (and not very popular). In contrast, if it was just launched I would be much more willing to try it out in spite of there been no clear examples of successful communities.
This may very well be revolutionary but my time is limited. Google searches for "sett blog" return nothing. #sett on twitter is more nothingness. It's ironic: I am not heavily engaged in social media at all, but turns I need social proof in situations like these.
