I guess this is a pertinent question in the context of such announcement posts.

What are the current alternatives for Bootstrap that provide:

* a good set of defaults with a sensible/easy grid system

* a modern look with readable typography and color choices

* a good enough set of controls

* support accessibility out of the box

* are leaner in size

* reduce/avoid the use of JavaScript (preferring CSS where possible)

* and lastly, very easy to get started with (and have great documentation)?
