(Note to executor - please update that when relevant)
As a general rule, I'll friend you if I think you're generally interesting to read, and I want to see your posts on my default view, or if I want to be able to include you in a filter. I rarely make locked posts. I don't mind bad language in general, but if you swear at me or my friends, then I will drop you from my friends list (if you're on it) and block you from posting here and anywhere else that I control.
