In case you've not seen it, we now have alternative data to compare against Janrain's from Gigya:<div><br></div><div><a href="http://info.gigya.com/Identity.html">http://info.gigya.com/Identity.html</a></div><div><br>
</div><div>Gigya of course breaks it down by provider, rather than underlying technology (which is how most people encounter the technologies — through brands) but this still provides us with a very important picture of the state of the art.</div>
<div><br></div><div>It's hard to break apart which services are using just OAuth or just OpenID, but by my estimation:</div><div><br></div><div>OAuth: 16%</div><div><br></div><div>* Twitter - 14%</div><div>* LinkedIn - 2%</div>
<div><br></div><div>OpenID: 38%</div><div><br></div><div>* Google - 17%</div><div>* Yahoo - 13%</div><div>* MySpace - 7%</div><div>* AOL - 1%</div><div><br></div><div>Other: 46%</div><div><br></div><div>* Facebook - 46%</div>
<div><br></div><div>Of course, if you consider that Facebook is set to move to OAuth 2.0, then that means that the final tally for Gigya is:</div><div><br></div><div>OpenID: 38%</div><div>OAuth: 62%</div><div><br></div><div>
