Part of my platform is that "No one should be made to feel stupid for their opinion in 2010" and I firmly believe that.
I was 16 years old when I joined Flyertalk and there were times when I felt the old "beat it kid you're bothering us" attitude from some of the older members. Now, 7.5 years later I try to keep that in mind when I reply to a post. It's very easy to cut someone down to size, to use the
face with impunity and to win your argument by pointing out someone's poor spelling/grammar or how you have more status then they do.
Unfortunately, too active a police force might stunt posting from the older members who have a wealth of information. I think if a gentle reminder from time to time as well as policing the use of the word "troll" and stopping threads a bit earlier (preventative moderation) would do the most good.
Also, members, especially new ones, should feel comfortable if they come to a member of the Talkboard or Moderation staff with their complaints they will be dealt with no matter who made them feel insulted.
