Ok, this is a joke played on an interesting, but controversial trend surfacing in the websites of minimalist Free Software lovers. They create a section dedicated to stuff they think that "Sucks" and stuff that "Rocks," and then ramble on about what's so great/shitty about it. The Suckless website's sidebar is probably the best-known example of it, but some others also use a similar structure.
Jokes apart, I also have some appreciation for certain Free Software that I could indeed dissertate about for a while. Who knows, perhaps I'll elaborate it into some real content in the future. But for now, enjoy these rocks!
