I think hiveonboard.com is the best current option, although I feel some of the explanations & marketing are still a bit too esoteric for the mainstream.

I think it’s problematic that both hive.blog and PeakD direct signups to signup.hive.io; I’d much prefer that to head to a single trusted source like hiveonboard. I feel like the instant bombardment on signup.hive.io of choices where to sign up, with some listing fees, etc. can be immediately off putting to curious potential users.
