Happy Birthday Vim, The Venerable Text Editor Turns 20
Vim has the kind of user lock-in mechanism  that big corporations can only dream of: modal editing.Once you get sold on modal text editing it becomes very difficult to accept or use any other editor that doesn't do it (which is pretty much every other text editor out there). Sublime, Textmate, e - all great editors. Don't feel like using any of them after 10 years of Vim.
