Quasi-anonymous blogs seem to be an ignoble specialty of our towns, Wi-Fi-enabled trolls cowardly throwing stones from behind the blue screen of their computers.
Do they actually believe what they say, do they affect anything, and do they even want to? One in Burbank acts like a private club, cheering on one another's takedowns like boozy frat boys. (The fights they have between themselves resemble this as well, but is a lot more fun to watch.)
I suppose you could call this local chattering class the digital evolution of the council gadfly, those souls who show up week after week to pick at elected officials regarding their pet projects, be they pension reform, leaf-blowers or puppy mills. I have no quarrel with gadflies, though, as they put themselves out in public, inviting discussion rather than quashing it.
