I've read a few of Joel Spolsky's (who has great name, by the way!) articles and enjoy them. Not only are they informative, but they are entertaining.

His latest is no different. It's about setting prices. You get to read about 20 pages of talk about setting prices. He starts out by laying out a good strategy. Then he picks that apart. Then he comes up with a new way. Then he picks that apart.

And then he finished by ensuring other bug tracking software companies can't compete with him!
