A little sceptical Nick?
Me too.
Sure, its concievable that Titan could have such activity. The right mix of volatiles and energetics could exist. I wouldn't call the softened radar image anything but circumstantial though.
In fact, you can even have features the look like flowing glaciers (organics or whatnot) formed by mechanical and volatile erosion or sublimation. There's a great example hear the southern polar deposits on Mars.
Could be, sure. But could be other things too.
