Activity digests being sent?

Is anyone getting digests from this site?  I'm a member of most groups and my profile is set to receive daily digests, yet I've never seen one.  What kind of content is included?  I'm still not sure how the stream relates to the other content types (discussion, document, etc.)

Update

10 days later, and I see activity in my stream over the past 10 days.  Isn't this the kind of stuff that should get packaged into a digest?  I'm still very confused about this.

Please reply to this and state if you're receiving digests or not.  Thanks!
