The reason Joseph Smarr came to all these identity meetings in recent months was revealed yesterday: Plaxo now does OpenID. This is great news.

It’s particularly gratifying for me: Plaxo was one of the very first companies I pitched LID 1.0 (Light-Weight Identity) to, the first URL-based identity scheme, at the end of 2004 — half year before there was an OpenID and all that happened since.

Congratulations, Plaxo! Keep it coming, there are a lot more things you can use OpenID for your particular business. (Those slides I showed you back then still have a bunch of ideas in them that would be a killer app for an on-line address book company like you are)
