Loving the service though, posting is real simple and the syntax highlighting is amazing!
Another thing I can't find it how to enable comments. I'd be fine with Disqus or any other 3rd party comment provider.
How about Google Analytics as well? How can I see which posts are being viewed?
Jekyllhub is based on Jekyll, which is a static site generator. The idea is that you have 100% control over the blog just by editing files - you can see all the raw files used to make your site under the "files" section of the sidebar. You can read more about how to use Jekyll here: (https://github.com/mojombo/jekyll/wiki/Usage)
If you're using one of the default templates, all the navigation links are in the file "_includes/links" - there's an example link provided, and you can add any other links you want (or nested links, or images, or anything else via HTML).
I'm still considering the right way to automatically add links, comment systems, or other add-ons like Google Analytics while still giving users all the code to their sites, but rest assured it's on the roadmap. Thanks for the feedback and suggestions, and happy blogging!
As I mentioned, and I may be wrong, but people interested in this service will most likely be people like me: They're aware of Jekyll but aren't familiar with it. They want the clean post syntax, syntax highlighting and light footprint, but they also want the comfort of managed hosting for it.
That link you provided for Jekyll usage is key, I'll have to read it. Maybe you can show it to new users so they too can easily find it.
