Found this at David Ascher’s blog, where he said :

It’s a brilliant paper about user interface design, or the lack of it. In the vein of Tufte, but much more applied to software. The tail end of the paper is a little too fluffy for my taste, and the paper would have been better without it, but that’s a minor flaw on what I hope will be an influential paper. I’ll try and get people to read it, but it’s too long for many.

It pretty much says it all. Don’t let its length discourage you from reading it.

I’m still a fan of OpenID, even though it lacks solid solutions to some of its problems.

Much has been said about risk of phishing and possible solutions, but I’ve been more ignorant than some to a transient nature of OpenID identities. Simply put, even if you run your own server, you don’t own your domain. You just rent it. Thus you don’t really own your OpenID URL either, which makes it a rather risky tool where some sort of permanent identity is needed.

There are plenty of cases where there’s no such need and OpenID is in my opinion a better solution to them than existing ones. But it isn’t good enough where something less fleeting is required. Maybe XRI/XDI is a better answer?

I don’t know. I’m still a fan of OpenID. It’s just a bit less useful than I first thought.

If implementation will be as good as intentions are, and there’s little reason to doubt it, then this thing will rock.
