Netroots Nation is an amalgamation of various liberal radical factions.
It originated as an event brought to us by the Daily Kos folks. Originally it was called Yearly Kos, then became Netroots.
From what I gather, they feel that they have great wisdom in the workd of Netroots , people on the net who crank out blogs full of liberal pablum as the answers to society’s problems.
I see their idiot show listed on the TV channels.
I have always avoided it.
I see that, as I surmised, was a wise choice.
