Interesting collection of seemingly useful mini libraries. Though the page has a visually appealing format (colorful boxes), it would have been a lot more useful if these libraries were grouped/tagged, and if the github stats were more visible.
Thanks for posting! Micro-frameworks are great for learning things that higher-level frameworks such as e.g. jQuery and Backbone hide from you.
Frameworks with the most features and the best (loudest?) marketing are usually the most popular (e.g. Rails and jQuery), but they might not the best tools for the job.
Instead of moaning about usability here on HN, perhaps you should put in a pull request for all your brilliant changes to the UI and they will be considered.
