...which admittedly doesn't have a great discussion, but it's not worthless.

The one you linked, though, is worth highlighting as a completely useless discussion, due to some meanness (mild as it goes), but mostly just a sad lack of thoughtful commenters, all of whom seemed to think several dozen redundant comments about the OP's headshot on his blog post was valuable feedback.

I didn't see any discussion whatsoever on the actual content of the OP.
