For dark matter developers, there is no "gatekeeper" since there's no gate they want to cross: those developers aren't posting, and they don't value the visibility that it sounds like you do.

You should listen to Scott's podcast: he has a wide array of guests, in many diverse topics (even topics that could be seen at odds with his employer, Microsoft). Most of them are people I've never heard of. If there are gatekeepers, Scott isn't one of them.
