Who cares if you have a good feeling about this dude? There are obvious and clear conflicts of interest at play here. If you care at all about quality, you'll wait before adopting new releases until bugs get discovered/ironed out. Don't adopt based on some dude's reputation when that reputation was built under a very different incentive environment.
