My name is Samuel Tesla, and only six months ago I was a vim user. I used mutt to read my email and keep track of addresses, BitchX? or X-chat to IRC. I thought Lisp was this crazy language that only researchers used (and had too many parens). I was happy in my ignorance.
But then I wanted an outliner.
All I needed was as outliner.
I found one for vim, but it just didn’t work the way I wanted. So I fired up emacs and played C-h t. That did it. OutlineMode did just what I wanted. I switched to emacs.
