> Tell me, what does it bring to the table compared to other window managers ?

This kind of window managers are often coupled to a programming language and the end user is expected to modify the source to their liking. For example, dwm is written in C, Xmonad in Haskell, awesome in Lua and there's even ones written in Scheme and Common Lisp. In all of these, the idea is that the source code is the configuration, and you're expected to hack on it.

Of course there's some appeal in just doing it in another programming language, even if it has been done before. A tiling window manager is a few thousand lines of code, so it's a neatly sized practice project.
