Ask HN: What should I use for feedback?

I'm working on a small personal website to host some small things (starting with a dashboard widget), so I'm looking for a feedback solution. Ideally, I'd like something with a free account, as I do not have much traffic thus far. I don't need a lot of features, and I'd like something where I could just drop a form onto the page vs. redirecting to a separate site for feedback collection. I'd appreciate any suggestions you'd have for what I should use, as well as what I should stay away from.
