"verify your SSH key through the OpenPGP web of trust"
Strength: OpenPGP is cool if you REALLY know how to use it.
Weakness: "vote counting scheme" does not sound too cool.

"use of an organization's own HTTPS site"
(advice from Stephanie Daugherty)
In my personal opinion, this is the best solution.
Weakness: basically nothing - it's very secure.

"use DNSSEC to validate SSH fingerprints"
(advice from Micha Borrmann / Jeroen van der Ham / john)
This is a good solution.
Weakness: HTTPS is more mature than DNSSEC(in my personal opinion).

"ssh-keyscan -p 22 domain.com ..."
(advice from Busindre)
It's the same as running "ssh" directly.

Check SSH(https://checkssh.com/)
(we made it)
Strength: this definitely stops ALL local bad boys.
Weakness:
While it's open source(and source code is less than 100 lines)...
We simply won't give you root password of the server(you don't own the server).
If adversary is EXTREMELY powerful:
It's better to set up your own Check SSH.

Best Wishes,
