I never understand moves like this by Twitter because for me, Twitter is a messaging utility, like email. You can use it from your desktop, browser, phone, iPad, etc. I rarely use Twitter the "website", so fancy iFrames on brand pages would be lost on me. Does Twitter really still view itself as a "website" and not a ubiquitous messaging utility?
