Examples of how to use Resources, Packages and flags

I'm trying to wrap my mind around the best use of the Resources and Packages content type as well as the flags feature. I've read the descriptions both provided in the install and elsewhere (for flags), but I'm having a difficult time trying to visualize the most effective use.

If anyone has used these features, or intends to, can you share some ideas of what you are doing with them?

I'm especially curious about the use of flags. It sounds like it has a myriad of different uses, but in what practical ways would it be useful for a news site?

Thank you very much,
Joe
