I think this is an important lesson for an awful lot of online communities -- in a public forum* some mild, warranted criticism is then published to your friends and they are then encouraged by the algorithm to put in their tuppence-worth. Should any of those be inclined to comment -- perhaps less sensitively, slightly more inflammatory -- then the cycle begins anew, with more fuel added to the fire. * Mostly looking at Twitter and Facebook with their explicit "engagement means my friends will see this" algorithm
