Finding online support for programming has undergone a change over the years. Usenet forums allowed people to organize discussion threads in the pre-web days (now Usenet seems to be only used for file sharing). Email lists were and still are also used, but lack a filter--you have to receive all the questions and answers to be part of the discussion.

I cashed in a lot of round tuits and updated the infrastructure on my site. One new addition is MathJax.
