This is very true. There have been many, many times when there's a technical article on the top of HN on a topic that I would never have imagined writing about simply because it seemed too basic or "entry-level". There have even been a few topics that I had actually considered writing about but dismissed it, thinking to myself "nah, everybody already knows that".
