There’s an interesting discussion on Mark Evan’s blog about the potential of a killer application for OpenID:
One of the biggest challenges facing OpenID is it’s a solution (universal identity management) looking for a problem to solve.
Sure, it’s a pain having to remember different usernames and passwords (unless you lazily use the same ones for everything) but most people don’t see it as a huge issue, which means OpenID has failed to gain much traction. And to be frank, that won’t change much even with major players such as Google, Yahoo and AOL starting to climb on the OpenID bandwagon recently.
One of the applications the Evan’s points to with some enthusiasm is PageOnce, which is a universal dashboard for the web.
