show which team we are each on

Wondering if a subtle way to indicate that we are aligned to business
problems and not e.g. products is to put our "business area" on the team
page?

* Anyone agree?
* Did I get the names right?
* We should do this for AA, too?

Also:

* Fix images so they are all the same height
update names

Jeff is now officially adminstrative overhead :)
