Re: [Resource Timing] Opt in vs Opt Out and initiatorType attribute

Hi Alois,

I've seen your bookmarklet and it's pretty good considering what we
have to work right now.

I'd be really happy working on a reference implementation with others
(mine's stalled a bit at the moment as I've just gone freelance)

Cheers

Andy

I think that this could be a great reference implementation. This could also be one of the deliverables of the working group. I know that there is also a Performance Interest Group and I was thinking about having something like a Community Group - like coremob for example - where we work on a reference implementation.
