Suggest caveat re: distrowatch

[nreith]

Excellent resources in this repo!

Just a small caveat. Distrowatch results are fun to look at but should be taken with a grain of salt because they are only based on clicks (within the distrowatch site itself) for each distro. This says nothing about how many times an iso or docker image was downloaded, or how many users, installs, or visits to official sites. By all indications Ubuntu and flavors and derivatives have the largest share of the Linux desktop market, and in servers Debian/Ubuntu are probably 35% or more, together the largest. In containers, Ubuntu and Debian and alpine are nearly the only game in town. Ubuntu is probably most popular by far for WSL2 as it's the default. Yet somehow MX Linux has dominated distrowatch for a couple of years. Many suspect cheating.
