More discussion isn't necessarily a good thing if they degenerate into flame wars, though that hasn't been the case here, despite a few somewhat inflammatory remarks by MichaelVassar.

Another explanation: if in a given week we have five great posts and five "meh" ones, you won't hear a lot of moaning about the low quality of the "meh" ones. It seems that this week we've pretty much only had "meh" posts.
