I write the simplest incarnation of an idea onto an app, and just share it out with colleagues. I have no expectations. I'd say my hit rate is about 1/5. I consider it very high. It's also that high because my audience is my coworkers and I have a good idea of what they want. It's also that low because I just cobble together stuff that barely works, with the ultimate intent to see if i'd get more questions/requests out of it.
