MG Siegler interviewing Adam Bain about Twitter’s promoted tweets in timelines:
>When I ask about the importance of exclusivity for the deals Twitter is offering (that is, will only Twitter get to offer them?), Bain says that it’s important to note that Promoted Tweets aren’t just about deals or offers — he doesn’t want this product thought of as “Twitter Deals”. “That’s one of a bunch of categories that consumers find interesting,” he says. “More than half of our launch is about exclusive content,” he says.

That addresses my biggest frustration with ads on websites: ad exclusivity. I hate it when I know that I *could* see that ad on another site. What a valuable thing Twitter is doing here. ((My entire commentary is called: *sarcasm*.))
