As you can tell from the screenshot's time stamp (June 8), this one has been sitting in my blog queue for quite some time. It's still worth posting though!
Here is a screenshot from a Promoted Tweet by Nike San Francisco. It's notable beyond the interesting fact that 1) Nike has a geographically driven social campaing (@NikeSF), and 2) they use these accounts to handle local customer service and promote national campaigns (interesting mix) With regard to Twitter... and more importantly... this is a great example of the power of a Promoted Tweet: - hyper targeted (in this case, local) - drives awareness and social activity: follows, replies, retweets, etc - but most importantly, its bigger than just Twitter actions (ie followers and retweets): YouTube is integrated directly and eventually this could be a registration form or purchase widget, etc.
That last point is quite powerful because advertisers do not have to value the campaign purely by Twitter-activity. That will (and should) be included - but it's potential is far bigger.
