My mate joined and did about three posts and then found more important things to do. But I'll let him off.
I often have geek e-mail conversations at work with former colleagues (who have been hived off elsewhere so I am a lone geek right now), and I'll throw in a link to a good argument on the Downs now and then. Mostly they tolerate this.
I suppose I could add an extra word to my name and promote it all the time.
