Hmmm, first of all, you need Ruby, and I will stop right there. I have no time to learn another language, or find another hosting company supporting Ruby.

Secondly, no comments to moderate? It's misleading. They use third-party to handle comments, right? Don't you need to moderate those comments?

Thirdly, I don't think it is easy to use. A regular John/Jan Doe will find hard time to write a post in a text editor, then send it to server for compilation.

If someone just want to write, don't want to worry about security and database stuff, wouldn't WordPress.com be a good option?

I will stay with WordPress, but thank you for sharing the information about Jekyll.
