Maybe I'm more set in my ways now, but I feel like distro hopping is largely a thing of the past. There used to be a ton of small distros with their own communities but they've pretty much disappeared. I don't know if it's the decline of the web forums as they used to be (which killed the small communities), or if people realized these were mostly just Debian/Fedora derivatives with a cool Openbox theme and some preinstalled packages, or if everyone just migrated to Arch.
To me, Crunchbang was the last of the fun distros.
