Anyone that wants to! If you'd like to run a weblog where users can join and participate with each other, or build a community, then Scoop can do that. Or if you'd just like to be able to post news updates, Scoop can do that. Basically, if you want to run a weblog, but don't want to write your own backend, or mess with some other one (many of which are complicated), then Scoop may very well be the answer for you.
