Sorry to lose you, Pam.
The PDA thing should probably be explained to everyone! When they show up in "Recent Posts," they seem a little out of place. A personal rant or whine makes sense when you realize it's basically a journal entry. That's what diarists do. If I had known about PDAs, I wouldn't tell people to buck up, buttercup. Diarists want commiseration not solutions. As an empiricist, I'll be careful not to post on them in the future.
An Ignore function would solve everyone's problems. It's funny that the Buddy List came before the Ignore List. It's usually the other way around.
