It would be nice to have a setting for reposting a stream item (status, photo, video, link, etc) that user can set at time of entry. Something similar to the 'share' button sharing.

For example, if I post a cat video to my friends, I would set the repost setting to 'Yes' because I don't mind if they share it. However, if I post that my dog just died, I would set the repost setting to 'No' because it's personal and I don't want it shared further.
