Praveen just blogged aboutthe launch of AOL's OpenAuthentication service. We'll be talking about this and more atWeb 2.0 Expo. Why launch another authentication service when wealready support OpenID? Because there are lots of cool things thatOpenID doesn't yet support. I think that it really supportsuser-controlled consent and permissions, for example. And Praveen isalready working within the OpenID community to add some of thesecapabilities as well.
