Your friend and mine, Rob Malda, has a very intense interview on ZDNET.

It is the usual gas-bag type stuff, except the second to last question:

ZDNET:  There is a lot of comment that gets posted that falls below the threshold line. How are you developing that technology to deliver comments so that readers get some information out of the boards?

CmdrNutloaf:  It's an ongoing project. It's just been evolving over the last four years. We are always changing things. We are certainly not done. The system works pretty well, but it's definitely not perfect yet. If you design a foolproof system, you get a bigger fool. We have a constant problem with people who are trying to break our system for no other purpose than they have nothing better to do--like their bosses haven't assigned them enough to do at work today, or that their mom hasn't made them mow the lawn, in most cases!
