My only time ever seeing and using client-side certificates was when I used StartSSL's service to get a free server certificate. It was an interesting experience and radically different from the usual experience of registering on a website with a username/email and password. Looks like the author says quite a few things about StartSSL's practices too. Just like the article laments, the UI for managing client-side certificates was very basic and not user-friendly; I was using Firefox. I do wish this technology was explored deeper by both webmasters and browsers; I prefer to have one or a few private keys instead of hundreds of different passwords for each website. I want to be immune to password keylogging and server-side database leaks.
