Recommended Mac Software

(a.k.a.: All right, John Hodgman, I switched. Now what?)

What I like most about the Mac is that there is this enormous subculture of nifty productivity software. These programs tend to be more numerous, easier to use, and of better quality than I have noticed for other platforms. Here is a list of software that I recommend. None of these are very expensive; many are free. Except where noted, I use all of these programs regularly.
