Here are some more links to OpenID knowledge:

• Could it be? Is OpenID Being Exploited By The Big Internet Companies? According to Michael Arrington, four big companies--Google, Microsoft, Yahoo and AOL--have all announced "support" for OpenID, but haven't put in the effort to make OpenID work to anyone's benefit but their own. Arrington suggests that maybe these Internet biggies are gaming the OpenID universe. A good read.
• Here's a nice OpenID resource: OpenID Status Check: A Guide to Getting and Using Your OpenID. Mostly, a list of links to OpenID resources, but not a bad place to start out if you want to try OpenID yourself. There are even some links to help you roll your own OpenIDs.

Any other good pointers? Let me know...
