No, but not because of the negativity (although I've been away for a year or so and am shocked how angry this board has gotten).
I've never recommended it to newbies, it's just too much info. This board is for people who think that whether they eat at BoG or Akershus is a make-or-break proposition. I saw someone wondering the other day if they had made a "terrible mistake" by booking a pirate cruise on their first day, before their son has had a chance to see the pirate tutorial. A terrible mistake? Really? I love the fact that you can get the info to any tiny nitpicky question here, really I do.
Actually, let me put it this way. I was talking to the person at my job who's in charge of all physical stuff--furniture, supplies, building maintenance, etc. He said to me once, everyone has one thing that they are very particular about (mine is buying those batteries with the built-in meters). And each person's one thing that they're very particular about is completely reasonable. But in a building of 200 people, those 200 completely reasonable things are completely overwhelming. And this board has how many thousands of members who may each have one particular quirk that's entirely reasonable but then multiply it by thousands ...
I do recommend WDWInfo, the informative side of this site, as well as AllEars, but honestly for most people I think the WDW website itself is plenty.
As for the negativity, the only person I know personally who is a bigger Disney fanatic than me is one of my aunts. I don't know what board or group she follows, but I know she says that FP+ and MBs are universally loved by the people in her group and she's super excited to try them out. And since I'm about to take at least one Disney doubter there, I am absolutely not telling anyone else to come here.
