I'd love to have 'asynchronous' node voting. It's annoying to have to click each node you want to vote on, scroll to the bottom, then click 'Vote' (sometimes I forget to actually submit the form when reading a long thread)

I read long threads entirely different. When I feel like voting on a node, I check the appropriate radio button. Then I go to the next node. When I'm done with the thread, I hit the vote button. Now my -maybe- 10 votes will be handled at once, thus less bandwidth than 10 asynchronous request on the server.
