Time to archive as many links as possible. I know some people who have used Mathb.in to draft (or publish!) short, insightful articles on various topics in mathematics. Since I last read these articles as an undergraduate student, it may take a while to find the links. Thankfully, there are at least two weeks worth of time to find them. Thank you susam for 13 years of continuous service.
