TapEngage (YC S11) acquired by Dropbox

Congrats to Sean! For people that aren't aware, for a long time, Sean was the lone product manager on Google App Engine, and he played a significant role in helping that product scale.

Perhaps Dropbox is moving more in the media center direction with their mobile apps, which are currently rather bland lists of folders and files. I could see them creating a much more interactive mobile interface to access your data and embedding ads throughout. I'd hate for them to go the way of online video and force you to watch an ad to open a file.
