Agreeing with Thomas:
Most of us when starting with a new software stack, look for the
latest version. I guess this is because it's fun to use the latest
stuff, and because it's annoying learning habits for stuff that will
soon be deprecated or raise an error.
We could explain why that should not be the case for scientific
python, but I imagine that new users will be a little puzzled and
maybe worried that we should be holding to an old version so long
after the release of the new.
I do believe we should have slight bias towards 3 rather 2 for the
sake of the health of the overall python ecosystem, which will have to
move. I don't know how we would know when we should 'recommend' 3
