Anyone on BombLogic PTC, I want to sign up?

Tweet

I have seen a site called bomblogic that looks interesting, if anyone has tried it, or is a member, I am willing to sign up under you, if you can tell me more. Do they pay, do referrals show, are there enough adds, what else do they offer (if anything), how long have they been around. I am a sucker for just joining anything I see, so let me know if this one is worth it.
