Why do I feel an obligation to software? There are apps that I've used for quite a long time and for some reason I feel obligated to continue using them. Tinderbox, TiddlyWiki, and Emacs are good examples. They're all great, but I rarely need the power afforded me and it's not always worth the added complexity. But I tinker, you know. They are part of my muscle memory. I have many (many!) documents that I created using each of them. I suspect that maybe I feel this way because they're also part of my identity. I've written about them often. I could simply stop using any of them and who would care? No one, probably, but since I can't seem to shut up about anything I would still feel guilty, somehow.
