Recently I was reading a forum thread that was talking about Linux distributions. Three comments in a row went thus (paraphrased):
Person 1: After 10 years of Ubuntu, I'm running Fedora.
Person 2: I gave up on Fedora back in 2003 and went with Gentoo.
Person 3: I used Gentoo for almost 3 years, but personally, I dumped it for Ubuntu.
