One idea I've been thinking of lately might also be a way of having a news module. The idea is really more of an advanced RSS module. On the admin side you would subscribe to as many rss feeds as you want, but then you would approve on a post by post basis from all the feeds, which posts go into the output rss and then this output rss would be the news feed. So you could post many items in the blog, but maybe only a few of those become news items by approving them. This would also allow pulling in news items from external feeds or other features in mojoPortal. For example I plan to add RSS for the Events feature so events can be subscribed to using an RSS reader like google Reader. But you could also announce events in the news module by the same apparoval process. So the admin page for this advanced RSS feature would have 2 panes, on the left you would see all the posts coming in from all the subscribed feeds and on the right pane the posts approved for the output feed. You would select a post on the left and either click a button or perhaps drag and drop to add it to the approved list. A good name for a feature like this might be RSS Publisher because you would selectivly publish posts into an outbound feed from all the inbound feeds.
Anyway its an idea I've been thinking of but not sure if/when I will get to it so if anyone else wants to build it that would be great.
