I usually spend the most of my time digging through DIY, Reef, and poking through if I can help a newbie every once in a while in NH.
I rarely ever go into Nano, or agressive since I am a reef guy.
Guess I vote NH's but if given the choice it would be #1-DIY, #2 Reef, then just poking around when bored or checking in. Same way I found this thread.
