There is only one board, isn't there? When there was talk of a new board, I checked some numbers. For the period 10/1-15, there were 50 questions asked on the old board with 52 answers. 19 (38%) received no comment. For the period 10/12-11/1. there were 58 questions asked on the new board with 41 replies. 32 (55%) received no response.
Since there were more answers on the old board than the new--104% to 71%--it just seems logical to ask questions where there is a better chance of getting a response. A couple of spot checks seems to indicate that this is still the situation. But I haven't been there lately and don't plan to go.
