I've been working on this thing on and off (OK, mostly off) for, literally, two or three years. The Bullboard. Sort of like a guestbook, or a message board, but not exactly.
I think the analogy (the billboard) is clear. Although I don't get THAT much traffic to dd.c the chances are still very good that, should you decide to drop a bit of wisdom onto the bullboard, complete strangers will read it.
Play nice now, hear?
