I defy you to post a program you've written in ed. I tried using it once. For some reason I thought it would be a good idea to use ed to write a clone of ed. Go figure. I lost interest pretty quick, but ed's lack of auto-indentation was a pain in the ass.
Someone needs to write a version of ed with all the things that make modern editors great -- auto indentation, code completion, syntax highlighting, and so on. Lulz would be had.
