@budparr : Ruby seems very pleasant and Jekyll seems awesome
@anthonyjsmith : majority of generator support plugin, but a tier plugin is not the same as an official functionally developed by core team
@all : as I said I'm not a web dev, and the thing I want the more it's simplicity. For some tricks Jekyll need to write short ruby code. But since I tried Hexo, I feel more at home with Hexo, it is simpler to manage for me and don't need code modification from me. Additionally Hexo is lightweight and less heavy to deploy on a server than Jekyll wich need a ruby env.
I'm not saying Hexo is better than Jekyll. They simply are not the same and I'm just feel more confident with Hexo for now.
At the beginning I just suggested that Tilt support more language than Liquid by default, and Tilt should be more interesting in the Jekyll core because the Jekyll configuration on GitHub pages don't allow you to use additional plugins, so if you want to deploy Jekyll on github (not only rendered files) you will have to use only Liquid and won't be able to use haml and other things that need external plugins ... That was why I said Tilt in Jekyll core should be good ... that's all
