I don’t actively use it, but I don’t see the point in deleting my account? My HOA is only on a Facebook group, so it’s the only place I can go to check for updates on some stuff (typically trash day getting moved, neighborhood pool stuff, etc). That’s the only use. My understanding is that Facebook tracks me even without an account so doesn’t really seem like I’m gaining anything other than good feelings by deleting my account.
It’s not like I’ve gone out of my way to delete my old Myspace or xanga accounts either, I just stop using them.
