Oh hey, it's you. I weirdly recognize your name from many many years ago. I have vague memories of dealing with you in submitting an open source patch for Django Facebook. Or maybe it was just a documentation change. Either way I remember you being very polite and professional. Just wanted to say that stuck with me and please keep it up, as I can see you're doing here!

I thought it was very thoughtful, detailed, well written and touched on all the points I would need to make a similar decision if it ever came down to it. Thanks for writing it.

Did the Go implementation of the ranked feed use the algorithm optimizations discovered while optimizing the Python implementation?

No most of the optimization were Python specific. But of course development time was a bit faster due to it being the 2nd time solving the same problem.
