I could ask over on SRS IRC if anyone will be interested, but hubski isn't big enough to suffer the cultural malaise that Reddit does, I think. SRS is able to thrive because there's a lot of material to work with, both because there's a lot of posts, and a lot of those posts are terrible due to Reddit culture.

Of course, I literally just joined to post this, so disregard if I'm wrong.

EDIT: Just read a few posts on Hubski. Maybe an SHS could be possible :V
