For the stack exchange fans we have around here... I recently noticed that there 
are a couple of conlang related questions on various SE's. They mostly are 
appearing and being tolerated on the writers' SE.

Here is a "filter" should anyone like to subscribe to them

And the conlang specific question site has 20% of the people necessary to go into 

I would not recommend posting conlang related questions on the linguistics SE 
site, although there are two Esperanto related questions there at the moment.
