I think it'd be nice to see more communication, but what kind of communication? As ecopoesis mentioned, https://webkit.org already exists, so I think what this post fails to do is actually say what it's looking for specifically. Is it conferences? A mailing list? Email addresses that are publicly available? The post itself is very flowery towards the end but mostly meaningless. Be specific.

Also not sure what you mean by "sign on the dotted line." The Safari developer program only requires you to create an Apple dev account and is otherwise free. So are all WWDC videos if you simply have an account, regardless of whether you're in any program.
