Minor nitpick with your comments regarding the use of classes for the grid system making your mark-up non-semantic. If you use the LESS or SASS version of Bootstrap and not the pre-compiled version of Bootstrap, you can use the internal grid system functions in place of classes on elements instead, thus making your markup semantic. I like the intent behind the Semantic UI project, but I feel like CSS preprocessors like LESS and SASS allow for semantic markup through the use of mixin functions out of the box without needing to use anything else.
