I use the FB app and when someone sends me and message and I RESPOND it checks it as read on the pc. But with like comments and such it doesn't. But it doesn't bother me.

yes. there is: I don't know which BB you have but on the Storm 2, I go to my messages folder or email folder where my facebook notifications are set up, select them all, then at the bottom, click "Mark Opened". Notifications disappear.
