A continuous roll of system message would show "activity", people having "fun" and so on. I think that would add more people than seeing a few names at the top of the board.
Exactly my thinking. The "get your name on the frontpage" would hardly apply with so many things happening and scrolling by, especially to someone stumbling over the AH site - all those literally hundreds of names would say nothing to him. But he could see that there is action, something that some other games only promise

Of course, us "regulars" could use it to lessen the effects of "cold turkey", when not being able to play (at work, on travels and so on)

Or you could see that someone is just rolling undefended bases in EW again... and feel tempted to jump in and say "hi"
