rugatu seems to be a bit dead actually, there aren't new questions being posted.. are there no other sites of this type? (I looked through the list on the wiki and don't see any)
I tried
http://coinworker.com but it rejected my work because apparently I did it wrong :/
Rugatu is alive. It's just that bitcoin isn't that popular that every Q&A site with karma would want to adapt it to give people tips for their information.
You bet, Rugatu is very well alive, ask something terabit and see for yourself
People aren't asking too much thinking they will be forced to put a reward on their questions, but that is not true, question rewards on Rugatu are optional so you can still ask like in other q&a communities, only for gaining karma (rep) points.
