Up to now I haven't named the authors in posts which I have differed with. The idea was that I was trying to minimize the possibility that my comments, rants, etc. would be taken personally. Instead, I would email the people letting them know (in case they noticed the tectonic plates shifting) so they'd have a chance to reply. This seems to have worked well enough up until now.
But it appears that lots of people Google themselves. Under my scheme, they won't find my posts that way. And when you consider all the spam prevention/bozo filtering available in email nowadays, I can't assume that email will get through.
So I'll be mentioning blogs and names from this point forward.
