A month ago, Pat Eyler (On Ruby), Apress, and I launched a Ruby blogging challenge with the question, "How Has Ruby Blown Your Mind?" .. There were 18 solid entries, and one late entry by Sean Hussey that I think would have won if it hadn't come late. The eventual winner was Ruby Blocks as Closures by Gabe de Silveira, and he wins three Apress books of his choosing. Well done Gabe!
