Actually I stole the user search code from Everything2 and nate had a random user from a list show up so I just substituted a list of the most active users at the time I added the code. Basically if you click thru on a writeup number on someones home node it passes a param for the user you want if that's empty it picks a random user from the list in the box. When you click the talk button the user param isn't passed because it's part of another form so you end up with a random user from the list in the code.
