I like that idea. I realize that this is completely unsolicited, but if you're looking to get to know the people that use Hubski better we have a lot of weekly things / clubs going on: Scifi Club Weekly "What Have You Been Listening to" Music Thread Hubski Drink Club (Mead is this week!) Semi-regular podcasts that are entirely user-made and always open to submissions for ideas. Weekly DJ which just got rebooted. We have a tag of the week which is a great way to find new tags that you might miss otherwise. There's been a lot of other stuff too, and if I've missed any other weekly or semi-regular occurrences, somebody please correct me. That's just to partially explain kb's comment about this being a place built off personal connections since that comment chain stopped in it's tracks.
I'll plug in the #photochallenge since my month is starting soon :) I also liked the #thingstolookat.uh_oh by uh_oh so hopefully we get some art fans in this influx to get the artistic side of Hubski a bit more active.
