Syndicating content is about providing new content and new versions of old content over a feed. This is traditional for blogs.

Syndicating content events is about monitoring containers and content for events: create, update, delete, rename, maybe even read. Or other types of events for other objects.

Syndicating events is easily confused with syndicating content because it includes create and update events, which makes it seem a superset of syndicating content. However, syndicating events does not require (though it allows) the actual content to be sent. For example, a create event might not send the content created; a delete event will likely not send the content deleted.

I think syndicating events in zope is difficult because I know of no persistent log of events (if you know fo one, correct me here). So we'll focus on syndicating content. We'll only syndicate content, of course, that has publishable content - so we won't be syndicating the portal catalog, for instance, even though listening for portal catalog events might be fun and profitable.
