How is it when used with a self-hosted plan? Also, my client machine is Windows - I see a guide to install Jekyll on Windows, but not sure if it will actually work (not officially supported).

On the theme itself, looks good. I like it.

For comments, is disqus the recommended solution? Does it slow down the system again with database calls? Security issues again?

I am also interested in having charts, but I presume integrating those would not be much trouble.

Thanks
