In case anyone didn't see it down at the bottom, this comment was left on the post:

  Ryan (& Everyone Else) –

  My name is Mike Vernal, and I manage the engineering team for Facebook
  Platform.

  I understand and am legitimately sorry for the frustration you guys are
  experiencing.

  I think there were three themes in this post — frequency of change, bugs,
  and documentation. I wanted to give you some more context on all three
  points, not as a way of excusing the problems you’ve had but as a way of
  adding some additional context.

  Over the past year or so, we’ve been pushing to simplify and standardize
  our development platform as much as possible, to address some of the root
  causes of the issues you point out here. For instance, we’ve been trying
  to move from FBML to IFrames over the past year because we think that
  IFrames are both a lot simpler to develop for and a lot simpler to
  maintain because they’re based on standard web technologies. We’ve also
  been moving towards simpler ways of integrating Facebook context
  (e.g., iframe-based social plugins) because they’re easier to use, debug,
  and maintain.

  Our end goal is to have a technology stack that is simple and
  standards-based, because we believe that’s actually the best way to
  address many of the issues you raise here.

  In terms of bugs, you’re right — we haven’t been doing a good enough job
  here. We’re working on this. We’re triaging bugs on a daily basis and
  working through the bug backlog. We’re continually adding more automated
  unit + functional tests to help prevent regressions and issues in the
  first place. And we’re working on our communication processes — the way
  the system works today, we actually copy verified bugs from Bugzilla into
  an internal bug tracking system, and we then use that internal bug
  tracking system to drive bugs to resolution. We don’t do a good enough
  job of communicating back to the Bugzilla bug the internal status and when
  we actually push a fix, which we’re working on. 

  In terms of documentation, again, you’re right. We’re building up a team
  and focusing on this as well.

  That said, actions speak louder than words. If you don’t see meaningful
  improvement by the end of October, please let me know. My email is
  mvernal@facebook.com.

  Thanks,
