[Xmonad] some basic xmonad questions

[brad clawsie]

i recently saw xmonad mentioned on reddit, but there was a quick
followup that it was not quite ready for public use. has this changed?

i am a current dwm user and generally love the tiling concept,
although i do not care for dwm's source code-based config system. will
xmonad support a plain-text conf file?

beyond being written in haskell, are there any compelling features in
xmonad (planned or to-date) to differentiate it?

how does xmonad compare to dwm with regards to system resrouce use?

thanks!
