I&#x27;ve been using BetterExplained to review concepts I thought I mastered (based on great test scores and grades) but years later realized I had zero intuition on. It has been, by far, the most useful single source of math content I&#x27;ve found on the internet. The world needs more people like you.<p>Two Questions:<p>1) What are your thoughts on interactive content like ExplainedVisually? I&#x27;ve been thinking about doing something similar for data structures &#x2F; algorithm topics. How much of learning math concepts is exploratory vs learn-by-doing?<p>2) Are you running BetterExplained as a side business, or full-time? And if you&#x27;re willing to share techniques and numbers for the entrepreneurial HN community, what are some things you&#x27;ve done to market it, monetize, etc and what were the results?<p>Thanks!
