Forums and lists that don't publicly enforce generally accepted rules of net etiquette tend to lose their more knowledgeable members. I, and I include myself in that class, have witnessed such collapses; they're not pretty. An example may be found at DigitalPoint's html/css forums.

I got to thinking about inline-block and inline-table and whether their creating a new block formatting context meant that float descendents were enclosed. The obvious next step was to set up a test case or two. Lo and behold, it does.
