I found a really great discussion on [Monomer-Dimer tatami tilings][1] and up-voted it.  However, it doesn't really have a question or answers.  It's still a great read.

It's not the first time I've seen [knowledge-dumps into MathOverflow][2] in the guise of questions.  (For some reason tilings are a frequence source of such posts.)

MathOverflow as it currently stands, is not always amenable to discussions or open-questions, as evidenced by the occasional closed questions.

[Quora][3] recently introduced a blogging feature, although it is build for philosophical and open-ended questions. And other users can vote on it.  

I wonder if any thought has been put into incorporating such a feature into MathOverflow where such posts would certainly attract readers and commentary.
