I based mine on some else his blog as well and open sourced mine as well in hope others benefit from it. I am glad to see most jekyll/middleman/octopress users open source their blog. Without it, mine wouldn't look as good as it does. What I have added is a way to turn jekyll a bit more into a CMS by automating the generation and deployment: http://born2code.net/blog/2013/05/27/simplify-your-jekyll-pu...
Jekyll is pretty neat. I too recently switched from wordpress to Jekyll and haven't looked back. I have open sourced my blog at https://github.com/abhayv/abhayv.github.io
