Ask HN: What's the best way to get early feedback on research?

I recently graduated and I'm currently finishing up some additional research related to my thesis, trying to get the work published.

My work is an empirical study concerning popular web frameworks. However, I'm not a web developer myself and would really like to get feedback from the web dev community on the usefulness of some of the ideas in my work before I submit to a conference or journal.

I've considered 1) writing a Medium article explaining the ideas and results from my paper and asking for feedback or 2) submitting a draft of the paper to Arxiv and posting a link on places like HN and reddit. In the latter case though, I'm not sure if it's acceptable to submit unpolished works to Arxiv, or where else I should be requesting feedback.

Is there a good and/or standard way to get early unofficial feedback from a community of developers?
