The general idea behind a thought I had to show random old ideas is that there are some really good ones buried deep in the exchange. SteenSchmidt brings up some good points related to that in this thread. Maybe something for the idea exchange in addition to (or instead of) showing random old ideas would be a live scroll showing the most recent kudos.
I think this can be done with RSS or even Twitter.
