Take that last utility program, for example. I realize I have a problem with formatting - my files are just formatted badly, that's all. I could go through and change them by hand but that would take aeons, and I don't know of any utility that would do something like that.
So I write one.
Half an hour later, I have a program that blitzes through 50 full-length novels in about ten seconds. Now the badly-formatted ones are great, and the ones I used to consider "well-formatted" are even better-formatted.
And that's just cool.
