The acquisition of Powerset could be a big boost to MS. It not only can provide a different angle to how traditional search is performed, but may also provide better "passive search" capabilities for other MS services.
Powerset is not a pump and dump like so many of the social networks.

Value is not all about how many eyeballs are on a site today, but how many can be on the site in the next few years.
