1. Too many petitions for causes: It is very good to be concerned about social and other just causes, but that doesn’t mean you can flood other’s timelines. Post it as your own status if you must, it gives others the option to decide whether they want to read it or not.
2. Updating status messages about things you did when you were under the influence of alcohol: An US teen got arrested after he posted a status message about driving drunk. His status said, “Driving drunk…classic ;) but to whoever’s vehicle I hit I am sorry. :P.” Not only is it uncool, it is often of no consequence to anyone but you.
3. Photos of you as a kid on your profile picture: Make an album, post those pictures to that, share that album, make it public if you want, but don’t make it your profile picture. Many or most of your friends didn’t see you when you were that young. A recent profile picture is easier for them to relate too and doesn’t leave them confused amongst all the posts showing on their News Feeds.
