I've started a blog where I post an idea a day, both to help me remember, but also to help train myself to think more creatively. A number of the ideas could function as startups.
A lot of the ideas skew towards tech and software, but some of them are actual products that could be built, and some are just half-baked ideas that might incrementally useful for an existing product.
