I would temper andyfzr's optimism a tad.
It's true that there are many great people on this site and the troll population is far smaller than any other forum I've visited. But not everybody on here is happy. Some of the other sections include rants, complaints, venting, etc. Some people come to this site to blow off steam after a hard day. Some people get frustrated by challenges. There are a few users who have become a bit bitter over the years.
Now, these situations are in the minority, but they do exist. Still, most of the people on this site are good, helpful folks. Personally, I try to follow a rule of offering more advice to others than I ask for help. But I can do that because I have a very stable personality. Feel free to ask for advice on whatever, but try to make sure you do it in the right sections (for best results).
Welcome aboard
