Yes I use it a lot... Perhaps not loads. We only use nuke now, shake is rarely opened. I guess I was lucky to learn shake as they are very similar. It made it easier to pick up nuke. I still don't know loads about nuke, but I can do what I need to for my job. A bit like Photoshop, I can paint a texture map but would propably make a crap jumble sale poster. btw, I think there are some nuke tuts in the free tutorials section on the escape website.
