Google Trends – Microsoft Cardspace vs. OpenID

Following a recent reminder by LifeHacker I have been playing around with Google Trends. Very interesting.

So, I plumbed in a query of Microsoft Cardspace searches compared with OpenID.

Question: What was announced or happened mid-August to cause the last peak for both areas?
