Ask HN: Do you seek quick/regular feedback on your project as you develop?

I'm working on a small app right now and keep waiting for two of my friends to log on so I could show them what I did last night. It's not ready for a "Review my app" post on HN yet and most of my friends/family aren't computer-savvy enough to give me useful feedback till the app is actually done. I wanted to know if I'm the only one who develops this way: I make a small new feature or two each day, show it to my potential users, get their feedback, and incorporate appropriate suggestions. Then I continue with the project. By small feature, I mean UI elements, basic functionality and layout etc. I don't want to make the entire UI or a complex feature and then find out my users don't like it. So now I wait for my friends to tell me if the logo looks ok, the colors are decent, or if the keyboard shortcut makes sense. I would love to form a group with HNers to test out little things in each other's apps on a regular basis and give feedback. It would be more like sharing with team mates and less like an organized beta-test. Would anyone be interested in something like this? The goal is to have more polished apps before we share them with the rest of the community and not waste too much effort building something that users don't want.
