Years ago, back when the CoH forums were up, I remember thinking that a poster who could have been a poster child for the over use of emoticons seemed to be posting quite a bit. It's been a while, but I think "GG" was posting an average of once every 21 minutes - and that average was arrived by dividing the number of posts into the number of minutes in a 24 hour day.
Every day, without fail, there were at least a hundred posts by that person (maybe it was multiple people with that account?).
Now, that was truly a bored person - or just someone easily interested in just about anything.
To be fair, I posted quite a bit in those days - once I learned they actually existed.
