Soooooo i don't get it yet lol

It'd be great to have some of y'all add me! (or whatever it's called... "follow"?)
Also, please can someone help me navigate the site and tell me what's "acceptable" to do?
Like, i was über-scurred to start +watching people here when i first popped up, 'cause i thought it might be like FB creepers who just go around friending anyone they come across. o.O
