Only on a handful of domains. Most site admins are fearful of HPKP. The mitm proxy I am using to post this message only has to exclude a small handful of domains from mitm decrypting. A bunch of google domains, eff.org, paypal, a few mozilla domain names, dropbox and android. To my surprise, no traditional banks, no money management or stock trading sites, no "secure" portals used by law firms to share sensitive files. The sites I would expect to use pinning are the ones that do not. On a side note, I would love to see a system that adds out-of-band validation of an entity. e.g. My bank should have a QR code behind glass on the wall that I can scan, import a key and further validate their site at the application layer, above and beyond HTTPS and CA certs.
