Same here. I'm making more software than ever, for myself, and I'm finding it incredibly useful. But even though I've been a proud open-source software developer, I'm not releasing this new code because I don't see the value in it: I won't get the credit (because I "only" designed it, and didn't write the code), nor will anyone else use it, and if they did use it, I wouldn't want another maintenance burden for myself. So it stays private.
