Officially supporting hacks makes no sense on any level that I can think of. But that's not to say that they couldn't put some serious professional Jelsoft-employed development into the .org site itself. They will be fully aware that the community contributions of third party developers increases their sales and makes them more money, how much I couldn't guess but I'll bet it's a figure that wouldn't be sneezed at. I'm sure the costs of running this site are not insubstantial but is that enough?
I wonder.
As for threads going unanswered, people do their best. I've had some answered some not, my last by an Admin no less on an entirely trivial coding question. Ultimately there's for more requests for help than answers given because the expertise can't keep up with inexpertise (not to mention that it's a good deal easier to ask a question than answer it

) and there's no real way to avoid that. Best thing you can do is remember that you get what you paid for and be grateful that there is such a resource as this forum and the internet in general.
