A few people have written previously about the choices that Google has made with respect to user identity (I have here, here and here). Dick Hardt has an interesting post with some of Google’s responses to questions about this.
I don’t know Ben Laurie’s credentials and I’ve not come across him before (but I’ll start reading his blog now) but reading his comments a couple of things occur to me. When Ben says
As of right now, what are the options? Is there any mature, reliable, secure identity federation mechanism that’s widely used?
It reminds me of the point I’ve made previously about competing protocols - until something gets enough traction to take a lead in this area then this response will be common. More importantly, however, is that whilst Google is developing its own identity mechanisms the people who should be taking a lead on this are arguing amongst themselves, trying to even define terms like federation and user-centric! Someone on the Identity Gang list made the point about terms being co-opted to sell an individual’s favoured products…
One final thing is that the “Identerati” (how I hate that term!) seems to be an insular (but somehow still fragmented!) group (the Identity Gang policy of invite only is only a symptom of this). The Whodentity list contains many familiar names, but Ben’s comments show that there is a much wider group who have an interest in this!
UPDATE: Kim Cameron also picks up on this here.
