Don't use it like twitter

I.e.
"Yo I'm at the grocery store xD"
"Yo I'm talking to this really hot girl/guy xD"
"Yo it's so cold outside" (and post accompanying iPhone weather screen shot)

Do:
Post interesting (and logical) pictures of you and cool things.

Check your pictures routinely to make sure others have not posted pictures of you you don't want up. You can either untag yourself or ask them to remove the picture.

Try to keep your friends to people you know. Pelicans may or may not be considered friends.
