Linux Lite is up to 18 million downloads

So Linux Lite is one of those Distros that stays in a corner and does its own thing.

Not one of the most popular Distributions and yet they have a download counter that is above 18 Million downloads.

Makes you wonder about Linux Mint, Ubuntu, Fedora, Debian and the rest. I know that download numbers do not equal current usage. For all we know it could just be 18 million Distro Hoppers cycling through the distros. But even if a fraction of those stay with the Distro you have to admit it is an impressive number.

How is Linux not mainstream?
