While the number of sites that support OpenID steadily increased in 2007, and users can choose among many providers, much remains to be done in terms of awareness and evangelism. Enter Spread OpenID, a campaign initiated by Carsten Pötter and Thomas Huhn. They set up a weblog, explain the technical terms behind OpenID, and maintain a comparison of OpenID providers. Since I know Carsten and his motivation from several blogger meetings, I wish Spread OpenID all the best. OpenID has its pros and cons, but Spread OpenID will certainly help to prove that, ultimately, it's a good thing.
