Ha! Didn't mean to be 'that guy'.

Glad to see this project in the works, very timely. Curious to see the results.

As I said, it's been awhile since trying Jetpack, but my experience in the past was something like this:

Page not loading, look in the console, 'waiting for connection to wordpress.com'.

Needing to set up a dummy wp.com site to enable functionality on my self hosted site also seemed unecessarily convoluted.

Anyway, with all the great features that Jetpack offers, I would love to see data showing it was not adversely affecting site performance.
