MMH purports to be educational, but that's just a veneer that makes the mockery palatable in polite company, and the veneer is thin — the last post I saw was an "educational" list that had McMansions with "LOL", etc., annotated. It was as educational as "People of Walmart".
[Edit: since people seem to need this pointed out, class != wealth; a journalist with a degree from Hopkins who writes for Jacobin, lectures at UofC, etc., is higher class than, e.g., the rednecks with big houses she mocks]
