The people who visit the Board are generally excitable and friendly. They also tend to try and give you things, if you prove a vulnerable target. They especially love it when people who had left return back to the Board, and even more so if they return to the PPC itself.
The Board currently stores roughly a year and a half's worth of posts (or, more precisely, 25,000). In order to preserve posts older than this, Tomash and Huinesoron have launched the Board Archive here and here.
