This is great :). I think I might have to go and retroactively remove my use of the word "pythonic" anywhere public, now...
Might I suggest a minor edit, though? Since most of these seem semi-serious (or at least, I've heard most of them proposed by "serious" people), the "namespaces" one seems out of place... how about:
Namespaces are a terrible idea, let's stop doing that because typing ``foo.bar`` takes twice as much time and energy to type as ``bar``
Better indeed; applied!# Ian Bicking
