Dave Winer writes that he stopped tagging the categories of blog posts. As soon as he missed one he felt guilty and then as the guilt grew he tagged less. He started just assigning things to a couple of categories and then not tagging at all.
Instead of making you feel bad for “only” doing 99%, a well designed system makes you feel good for doing 1%.
