I use dwm, in particular a Debian netinstall with no desktop environment. Simply install X and dwm. I have my own fork of dwm with my customizations on a separate branch.
I can update dwm by pulling master and rebasing my branch on master. Has worked since 2006. With that being said, dwm hasn't changed much since 2006.
That's a common argument which is essentially, "I grew up and needed to be productive so that's why I don't use tiling window managers."
It's ironic and silly because I use a tiling window manager to _be_ productive. I have used the same settings, window manager and configuration since 2006. That is exactly why I love it, it's stable as can be and I can rely on it forever (at least until X11 doesn't work anymore, but I will probably be dead by then).
