I can see it coming. There are indications of a wave of incivility erupting in the blogosphere of make-believe. I sense it when I visit other sites. It seems to be kind of cyclical. Some bloggers and commenters go through an 'all- sweetness-devotion and humility' period, eventually returning to their hyper-critical self... until suddenly, WHAM! The gloves are off! This is about the fourth time I've noticed it in my year and a half of blogging.
Some bloggers, and obviously commenters, seem to have a lot of issues - other than the subjects they post about. (Although it's fun to watch, I think I better be careful.)
