Views Bulk Operations is an extremely useful new way to bulk manage content from within views. Consider it a much more flexible version of admin/content/node.
It incorporates both node operations as well as actions, so it is very possible to do just about anything you want to many nodes at a time.
On my latest project, we’ve come to depend heavily on it for managing node properties and queuing nodes for actions. Some folks might be surprised at how useful this can be.

I’d like to give a brief demo and get feedback.
