I continue to be amazed by the people who install "random binaries" via PPA.

I guess I assume that if you want cutting-edge packages you'll use a cutting-edge release/distribution. If you don't, and you want something more recent then it seems to make sense to make your own packages, or install locally via gnu-stow, or similar.

Debian/Ubuntu packaging is far too difficult and thus creates bad incentives for people to install software from untrusted sources.
