I read here a lot, and spend most of my time here on the DVC boards.
I sometimes check out the Trip Reports area. I actually started there years ago, researching a trip I was planning. I found that in reading other people's trip reports, I picked up lots of tips.
Trip Reports can give you an opportunity to see how families, similar to yours, enjoyed their trip and why (what worked, what didn't, what they'd do again, what they would skip.) So, sometimes I skim around over there, and I usually write up a trip report of my own when I get back. Which reminds me, that I need to finish the one that I have in progress.
Otherwise, I stay away from the CB, other than one thread of DISers that try to stay in touch with that I originally "found" on the Trip Report boards.
I usually don't read threads on the Theme Park or Restaurant boards unless I am looking for something specific. I do however, watch the Food Porn thread over on the Restaurant board. I like to check it out to help me choose my ADRs.
