Hosting Matters. They are the best.
They host my dinky personal site (along with major sites such as Instapundit) and they treat everyone the same regardless of whether or not you are a big fish. I never have downtime, never have issues. I've tried other cheaper hosting companies and I always have problems.
Annette, the owner, is great. She has personally responded to various unique requests I've made for funky DNS changes and other things.
