Normally paying for links to your website or blog is a quick way to lose money (and arguably Google ranking), but in this case, I think Google will oblige. Ruby Inside, a blog devoted to the Ruby on Rails web development framework, is offering $100 for the best Ruby on Rails how-tos and tutorials if you get your post in before Sunday. What a great way to encourage more documentation on the web!
Normally I wouldn’t link to such a brazen request for links, but
a) I use Ruby on Rails for web development and have been disappointed only by its lack of documentation and my lack of skill
b) They’re offering $15 just for linking to the contest
