I do, when they make themselves available through online discussion groups. Otherwise I don't bother them (how would you feel if you received 1000 emails telling you of the same questionable error?).

or note them in your web journal, assuming you have one.

I don't. If I ever do, please kick me off the Internet ;-)

The second part of good design is that sometimes you have to do something that isn't good design, and that is good design.

Putting aside logical fallacies ;-), I'd like to think otherwise. Since wanting to think otherwise hardly means its true, could you provide an example?
