OpenID: Growing Quickly
I mentioned yesterday that David Recordon and Johannes Ernst had a great article posted on the ZDNet blog. It got picked up this morning by Slashdot based on some coverage from Internet Identity World yesterday.

While at IIW, I gave a talk on adoption rates of OpenID and some other trends we’re seeing in open source use. I mentioned that we’re seeing 5% growth of sites that are supporting OpenID every week. That means, we are seeing more and more new sites that support OpenID every week. As of this writing, that number is at 561 total sites. The key here, and I mentioned this in my talk, is that this is from the perspective of MyOpenID.com (this is the OpenID Identity Provider that we run). That means this is not all-inclusive. The odds are that there are actually more. See the above graph for clarification.
