为什么会有http://asciicasts.com/ ，套用作者的原话

About ASCIIcasts

I really like Ryan Bates’s Railscasts, but videos aren’t the easiest thing to search through when you’re trying to search for a single tip or line of Ruby code to add to your own site. ASCIIcasts are text versions of each Railscast, each with a link to the original video. I hope you find them useful. You can keep up to date with new episodes on Twitter.

或许是这个颜色比较符合我的口味，比看 railscast 的 ascllcasts 更专注一点，有木有同样感觉的童鞋？
