A central theme running through all the utilities in Flock is the ability to share information with friends. In order to facilitate this, Flock employs a clipboard system that allows users to drag images, files, and website links onto a clipboard, and then share them with their friends through any of their social sites and supported Web-mail sites.

However, there are a couple of obvious limits to Flock's abilities. Primarily, there is no support for MySpace or Bebo, two of the largest social networks, or for any instant-messaging clients. Hardin says that MySpace integration will be coming "in the next few months . . . It will definitely be out by Q3." Instant-messaging support is also in the works.
