They seem to be quite here on Bitcointalk, I don't know if they have even an Announcement thread or a Sig/bounty campaign. Paybear seems to be promising but I think they lack people's awareness of their product.
Maybe because they're just isn't legit? I have looked into their website and they seem to good to be true. The service they offer is at 0%? Don't know but I think they aren't legit for me.
LOL. Think again. Paybear didn't say the 0% is forever, take a look again to their website. The 0% service fee you're saying is just for the intro or beta period of the service. After that they'll be asking a service fee but lesser than its competitor right now.
