I spent most of yesterday implementing openid on a site I'm developing. The problem is not the underlying mechanism but rather the way it's been presented on most sites. Remembering an openid url is counterintuitive for most people - you have to explain too much to all but the most technical users in order for them to know what's going on. But now there has been some progress: Yahoo became an openid provider a while back, and they allow you to log in with their openid by simply entering "Yahoo.com," you don't even have to remember your openid URL. I also used JanRain's ID Selector Javascript widget to make the signup form a little more intuitive: http://www.idselector.com/ http://www.idselector.com/ So really I think openid is getting much better as it matures and its developer community tweaks it and the tools around it. If Google and Microsoft fully get on board (which they are promising) I think it will see pretty widespread adoption.
