The flip side of ADD is that you actually focus on stupid stuff faaaaar too much
I have a tendency to prejudge posts like that too, but I usually still look at the first sentence. Like right now on the other thread, I saw Quetzel open with a nonsensical "realisation" that laws are generalisations, and decided that he might as well go on my ignore list now.
Occasionally people say good stuff or provide good links that can surprise you so I don't want to miss out completely.
