@ncoghlan does this list seem correct to you?

[pradyunsg]

@jonparrott What about https://www.pypa.io?

[theacodes]

@pradyunsg it's there. :)

[pradyunsg]

Oops. My bad.

[ncoghlan]

@jonparrott Aye, that list looks good to me.

I've made pypa/pip#4758 for this. It's pretty much ready; I'd appreciate some pointers on what should be added on the landing index page though.

@jonparrott I've updated OP to reflect that pip master has switched. :)

awesome.

Can we get a package a release for this? Being able to only install it from git is a major impediment with progress on this task.
