"Postworthy": an activity, occurance or idea worthy of posting on your facebook status. (Becky)
For the record, some folks have an unfortunate idea of what is postworthy. "I made a big poopie" will never EVER be postworthy.
For me, things that are funny, or make me look silly are postworthy. My (or your) opinion of politics are boring and make me (or you) sound like a jerk. I have a blog to post my boorish opinions on stuff only I care about.
