I think one point which needs to be emphasized more is what does python 3 bring to people. The" what's new in python 3 page" gives the impression that python 3 is about removing cruft. That's a very poor argument to push people to switch. I doubt "porting is easier than you think" will convince many people if they don't know what the gain will be. For example, porting numpy and scipy to py3k has been easier than I thought, but besides making it easier for other people to switch, I can't see *any* benefit. That's bound to frustrate people.
