Thats fine if it works for you. To me its just noise that pollutes all the things I want to do. You don't have to be a hermit. If avoiding Facebook makes you a hermit, than I think we failed and we're depending too much on a single technology to be social, that doesn't sound right to me.
Attending fewer events
Misreading others' intentions
Yeah, I think I'm gonna stick with Facebook. I don't need even MORE reasons to be a hermit -- it's already my natural tendency!
