@venam, i did for the same exact reason. i also use the default emacs mode. i tend to spend a lot of time on a lot of different servers, and the default is emacs mode on every single one of them. so instead of always switching to vi-mode, i decided to learn the default. it has the added benefit of getting me used to applications that are also readline capable. this way i can use C-a to go to the beginning of the line, C-e to go to the end, M-backspace to delete a word with separator back, C-w to delete a full word back, C-p for previous history, C-n for next history, etc. it is all so very helpful. (could also use vi-mode within a cli app, but would have to change the mode there as well)

except when you get so damn used to these keybindings, and you attempt to delete the last word you're typing in a reply on the forum using C-w...

but the defaults are why i also use bash everywhere except my personal laptop. it is the default shell on all of our servers. and i follow where the wind blows, or something like that
