Does this support multivariate testing?

Sixpack doesn't currently support multivariate testing, but there have been proposals for it in our github issues. I'd imagine that it gets added at some point... until then, we accept PR's!

Major congrats to one of the most outstanding teams I know

This article seems to ignore cost. I think a pretty fundamental benefit of a simple latex condom is how cheap it is.

Trying this very much makes me dizzy and a bit ill. And I'm not the sort of person who gets motion sick.

What is the ostensible reason these things are being hidden?

It would be cool to establish a marketplace for help on top of this. i.e. I can pay $1/min for someone's time on demand to get help.

If that existed, I would have spent a ton last winter when I was learning Obj C.

maybe they can integrate in someway with the upcoming Google Helpouts.. (using an API that will be later on shut down by Google, of course.. :))
