If I wanted to link to the pages I like, or just find useful, I would have to make a whole page full of buttons, banners and links. :P And the point was to put one, max two buttons, on the main page.
Apart from that, the webcomic is addressed to a general public and the idea is, that if someone likes my work, he might want to check out, what's the deal with Linux, OSI/FSF and the Penguin( Tux
). I wanted the button on the page to link to a site that could easily accommodate such needs, and help such a person to learn more. Although I have very little knowledge of such pages, since my very first experiences with Linux come from my university, I realize such sites should be promoted. If I had a button leading to SuSE Forums, or LinuxQuestions (pages that I use and like the most), that would not exactly accomplish my goal. That's why I asked for some suggestions
