Giles Turnbull writes a fun little piece on his love of text editors.

If, as I hope, you are just like me, and you have a strange fascination with text editors too, perhaps you might like to join me as I take you on a tour, line by line, character by character, into the wonderful plain text world I've explored.

I also have a fascination with text editors.  My favorites include UltraEdit, Vim, and BBEdit.
