Comment it matters a lot (Score 4, Insightful) 545
Touch typists generally use more verbose variable names and more comments, because it's much more natural for them to type a lot of words. This makes their code a lot more readable, which saves money in the end since a *lot* of the cost of software is in maintenance and the only performance factor that really counts is not cpu cycles, memory usage or bandwith utilization, but euros, dollars, rupees, yens or whatever your legal tender is. The programmer's time is (one of) the most costly aspect(s) of software development. A crufty codebase is much easier to read and maintian with comments *really* explaining fixes and variable names explaining what they're used for. I see so much code with comments like '// Issue #24654' or variable names like 'i' or 'j' in functions that span more than 50 lines (or whatever fits in one screen).
Of course there's more than typing speed involved in making maintainable code and I'm sure there are non touch typists who force themselves to make their code readable, but being able to type fast without thinking helps a lot.
