A little over a year ago, I wrote about Facebook's post-logout promotion of Facebook Mobile - which helped to significantly increase iPhone usage (+20% in a week).
Meanwhile, another giant social / mobile player is now doing the same. Twitter has recently redesigned their homepage and, in an effort to view it, I logged out of my account today. I was greeted with the following screen:
For Facebook, the unit's efficacy makes sense because, despite targeting logged out users, it is still highly targeted ... and therefore still counts as "in the river marketing". So why shouldn't this work with Twitter?
And Twitter's approach to showcasing their App across all platforms is equally compelling (and reminiscent to Amazon's marketing).
Also interesting is the dual action item of "download now" and "use via SMS". Both actions route content directly to your mobile device either by email or SMS. Once there, you are either directly engaged or Twitter is able to direct you to the appropriate application / app-store. Smart.
