I've been keeping a gist of web product guidelines for myself. It's pretty much a list of stuff I tell entrepreneurs when they asked me what I've learned from Pownce (from a product point of view) and also what I try to remind myself when working on new projects. I thought I'd re-post them here for fun. If I'm missing anything, be sure to comment.
I'm very interested in improving my product development skills, but I don't really where to go to learn more. Any suggestions?
