Sarah's Question #1: Facebook Etiquette

So I was about to sit down yesterday and write a long diatribe about some of my lingering social networking questions, but then I thought, oh what the hell- I'd rather just say it out loud. I know I rambled a little too long (what can I say? I'm a yapper). I'll shoot for no more than 90 seconds next time, and maybe use Seesmic so you guys can comment with video? Thanks in advance for your participation! Oh, and I already know that my nose looks like it's made of silly putty, but I also have an excellent sense of smell, so there.
