It's a tricky one.

As a product owner there are massive benefits to having Facebook accounts over your own login system. I don't like it either but being able to tap into friend networks & social activity streams is really useful: http://blog.intercom.io/designing-for-viral-distribution/ http://blog.intercom.io/measuring-viral-distribution/

Spotify is the poster child of the sort of success that it brings, pretty much every interaction (play, fave, playlist etc) is streamed to FB constantly spreading the word about Spotify.

Not saying it's "cool" , just that it's a very sensible thing for a business owner to shoot for.

I'm in that camp.

It's also interesting because I close the tab on 50-70% of the "Hey HN, look what I made" posts for the same reason. (requiring Facebook)

Yup. It's even put me off telling some people about it, they don't have facebook, they're not amazingly technical and I'll have to talk them through the sign-up online.
