> The problem is that solutions like this aren't realistic. If Twitter's going to show ads and other content like cards in their stream, advertisers have to have confidence that the content and presentation will be preserved. The only way to truly do this effectively is to control how your product is presented in all cases.

Thank you. It amazes me how people miss this. Look at it from the perspective of Twitter's customers (advertisers). Would you buy an ad without seeing exactly what it looks like, or without knowing with certainty that what they show you is what winds up in front of the users eyeballs? Having worked in advertising, companies pay attention to every last detail of an ad piece. This is the exact reason why Twitter has gone this way. That have to sell themselves to companies as trustworthy partner.
