I am guessing it could have a lot to do with the fact that Dave Winer is known to be a bit of a crank! He's historically gotten into a lot of ugly arguments, regardless of his age.<p>It seems crazy to me now, but I worried most about ageism when I was around 38. I had just started a job in the Bay Area where almost everybody else was in their early twenties. To the extent that there was a problem, it was all in my head.<p>I am now 46, I have a much better perspective on it, and I don't think about it at all. I suppose it is possible that I have been discriminated against during job searches, but I've got plenty of more important things to worry about.
