It's kind of off-topic, but I found this statement from Jason weird:
"functioning as a real contributor when there’s an issue (e.g. don’t report a bug unless you have a patch)"
Doubly so as later in the same post he's asking Bruno if the failures he's talking about are real or hypothetical. In other words demonstrating that bug reports are valuable even without patches (though of course their value can vary wildly).
Bruno was saying that Google are the gatekeepers of V8 and that if they didn't plan to support server side use of V8 that it'd be hard to contribute to the official codebase. Jason said that not only did Joyent have many V8 committers but additionally they've worked with the Google guys to submit real contributions. This would mean that any contributions they make in the future are far more likely to be accepted due to both the quality of work and the previous credibility they built up with the Google V8 team.
Simply put you're a lot more likely to accept a large feature patch from someone you know and has contributed previously than from someone who doesn't contribute. He doesn't mean to say bug reports have no value if there's no patch.
