As it is now the front page of PyPi https://pypi.python.org/pypi gives us more information than the front page of Crate.
I like that it's quick, PyPi is a bit slow for me at the moment.
I also like the info page for a specific package (https://crate.io/packages/docopt/#description), it's nice and informative, quite easy to read but I do not like that you have to click the info tab to see the classifiers (which python versions it works with, among other things).
What is the key arguments and features that should make us want to use Crate.io over PyPi?
I mostly interface with PyPi via pip on the commandline.
Is crate supposed to be a drop-in replacement? Can we just make pip work against a different base url? Will you launch your own pip replacement?
How is Crate.io better than the current PyPi? The website does not mention any of this, it barely contains any text.
</ramble>, I've just wrote up a few of the questions I had while checking it out, sorry if it's a bit incoherent :-)
