On HN you'll get a lopsided response to this because smart guys think Google is evil.

I'm not that smart, so I think Google is far more trustworthy than the other sharks out there.

Even though I trust Google more than most, and I don't think using Google auth is a security or privacy risk, and Google auth is almost certainly more secure than bespoke auth, most regular people probably aren't clear on how this works.

They might be reluctant to type in their Google password on what looks to them like a third-party site.

The HN objection is more likely to be the privacy/tracking implications of logging in with Google than that Google is evil, in my experience
