I like writing, because of it structures my thought and forces me to think it through thoroughly. It is also greatly satisfying to share the lessons learned down the road. So I don't think you shouldn't write for others. In the end, no one is Spolsky or Yegges except for themselves, but we shouldn't underestimate the benefit to the masses that may learn from you. I am by no means an authority, but I get a few appreciative emails every so often and that brings me great joy.
