I myself am not a Crunchbang user, I have always made my own forks of various
other platforms that are similar (better imho) to Crunchbang. I now want to
proceed with these principles on a completely free system.
I like Crunchbang-esque distros because I am a very minimal person. I like
minimal environments, simplified menus, slim designs, and distros that have
superior and more software choices out of the box.
Despite what you may imagine, the official Crunchbang was not very
lightweight. Any debian or ubuntu-based system running Openbox will use less
memory. So I figured Trisquel with Openbox would be a good candidate.
