That sort of spiraled out of control with what TH could handle. It basically started with one small group of profs (I think entertainer, dancer, and musician) submitting some questions to the devs, it sounded like a good idea, then they tried expanding to all professions. But basically the stuff that the players were asking weren't things that the devs could really answer, plus it ate up a lot of TH's time (and the devs he was passing them on to) at a time before Tiggs arrived to take some of his load off. So they decided that it wasn't worth pursuing at that time.
On the other hand, the devs did ask all the corres a week or so ago for 3 questions each to be answered by the devs (although specific to CU changes), and those have been filtering back, so communication isn't completely severed.
