As far as I know, "poking" still exists on Facebook, IF you can find it.

Poking (or some version thereof) might be a really handy tool (providing it doesn't eat too many RCs) to help bring life back to accounts that seem to be going dormant. Since we don't really have a true messenger system here (I don't count wallet memos), a "poke" might be something really useful. Especially if you got something like 80 characters of (non-hyperlink) text to add to the poke.
