Funny, I was thinking about a similar aspect just yeasterday.
This IS a great board and will always remain that way as long as Mike M has control, IMHO. And, personally, I haven't noticed any negative postings here; however, it is very true that negative and/or personal adjenda postings will most definitely ruin any board, just as it has with the TM Forum.
However, in regards to participation, I have witnessed every board in our Industry is way down....in the USA. In the UK, it seems that they are still bustling for whatever reason. I think only as a guess, that many in the USA are in a "holding pattern" ; the soon to come primaries, the eventual elections, and just over-all depression over this stalled economy and cureent elected leaders.
My prediction: "IF" we make a hugh change in Washington, and "IF" the elected Leaders do what they have preached they would do (cut the budget and stop spending), the stock market will take off and our economy will boom once again. Businesses have not reinvested over the past decade plus, and new start-ups have stalled. Inventories have been depleted and assets/material items are long over-due for replacement.
In the end, "IF" the above happens, this board and others will also be in demand!
(I left out many specifics, but you get the point, I hope)
Best to all;
