Daniel Kehoe hasn't finished this ambitious comparison of HTML5 front-end frameworks, but it already shows great promise, and would benefit from your discussion.
Daniel's specific target audience is Rails developers, so he's picked his frameworks accordingly. He approaches the frameworks as follows:
The comparison format is particularly useful, even though the information is not yet complete. Rather than simply list each framework, with features-list attached, Daniel lists features first, then compares frameworks' support of each feature. The web developer's question isn't e.g. 'what can HTML5 Boilerplate do for me', but rather 'how can I easily put my page into a grid' -- focused less on the tool, and more on the result.
Right now most of the info pertains to HTML5 Boilerplate (which has its own separate page), Twitter's Bootstrap (which I've used, and found quite helpful), and Zurb's Foundation -- three of the most popular and feature-rich frameworks available.
Definitely worth a look, and probably also a collaborative update (especially if you like the feature-centric approach).
