My idea for an addition to the site would be a section where you could keep a log. The idea with this is that people who would like to share their work has an opportunity to do so. Also, this log could be like a "workout" logbook where you share what you have done during the day math and physics related - e.g. which problems you solved, what you read, and general thoughts related to these topics. People could then comment and give encouragement and suggestions. I would start a log immediately.
