Nice thread. Hope I don't come off as harsh, but there are a few things that I'd change if I had the chance.
For starters, the amount of clutter from multiple threads, or topics that have gotten out of hand and relate nothing to the OP, is astounding. The search feature here (as in most other forums) is becoming more and more pointless to use, and I feel like I'm in one of those Bing commercials full of useless information.
I can't stand the amount of threads starting out as questions for Google Voice that end up pages full of "send me an invite." I've noticed an "official invite" thread, but I don't see it being enforced through other threads. maybe if an "official GV questions" thread were made as well, and other threads were appropriately merged and enforced?
There is an incredible amount of threads for EVERY SINGLE LITTLE THING on Froyo. I, along with some other people, will not be using Froyo until source is released, and it would alleviate the headache of going through pages of Froyo to find something relevant to me if it were separated from 2.1 topics.
The "why did my thread get deleted" thread. I don't think I need to explain what's so annoying about this one, but is there any way when a topic is deleted to PM the original poster to let them know why, and to prevent this annoying annoyance? Or at least keep the thread up, but locked with a reason why, for a day or two before deleting (unless of course it's THAT bad). But this type of behavior seriously needs to be discouraged. It just brings a tiff among members and an excuse for flaming.
This one is just me complaining, so no one take it seriously, but can we delete every post that tells someone to use Handcent as a way to fix their text messaging problems?

I personally don't like anything about that app, and it's annoying how so many people call praise to it, as if it's a messiah of some sort.
And, to end this, I'm just going to say there aren't nearly enough "I hate Apple" threads here. (PS, I'm being sarcastic)
