Now it is fairly well known on t'internet that for reasons best known to myself, I am a full-on 100% complete-and-utter Facebook refusenik. All the same, I am aware of some of the social functions provided by the aforementioned site, not least the idea that you can send someone a short greeting/message/reminder known as a 'poke'. Having given this some thought, I have come to the conclusion that this must be the equivalent of a Post-It note on your computer screen when you return from a lengthy liquid lunch which, in my experience, is never A Good Thing.
#2: You have been poked
And anyway, it sounds rather rude :)
