Qqueues has had makeover and has a nice, clean look. I never really got into it before, I don't know why. I know some of the good people here use it for their AF / FV lists, and so I thought I'd mention it here.
The tags can be used to dot tasks (its quite easy to do), and any number of lists seem to be possible, including assigning tasks and collaborating.
I use it, although I really wish there was a native android app rather than a mobile web version. No matter how well done, it's still not the same as the native one. Gqueues isn't as natural to use for FV as say, Wunderlist, but I really like having my tasks appear on Google calendar, and Gqueues does it better than any other software.

I'm back on board with GQ and giving it a go.
