It is a great event, as others here can attest. We know that people from Apple and Mozilla are registered, and we'd really love to see some chromies there - so don't forget to register!
This year there is also a proposal to hold a special WHATNOT meeting, and we are happy to be a W3C endorsed conference https://www.w3.org/events/conferences/ - so if you'd like to meet up there, let us know.
