Hi, I've opened a bug about a ViewportObserver API that would allow
developers to receive a digest of what nodes enter or leave the viewport
(similar to MutationObserver).
The bug is on the w3's bugzilla:

The discussion didn't go really far, it stopped a year ago but I've seen
similar ideas pop up in different places(e.g.
http://lists.w3.org/Archives/Public/public-web-perf/2013May/0027.html ).
I'm now searching for people who could help me move this idea forward.
Who should I ping/contact/harass?

Thank you in advance,
