Well, I'm thinking for this idea for some days now : why not have a RSS feed for recent submissions?
I'll explain for others who don't know very well what or why the rss feed could be interesting :
A RSS feed is - to be simplist - a page where all recent news are linked. You can have rapidly all new recent submission like articles for newspapers, new subjects for forums communities or why not new recent submissions for us in this case ? It would be fast and more easily to follow the news submissions on MT.. ;)
We could watch or have a few informations about these recent submissions for one day, two days, a week and a month like RSS Viewer for Safari on Mac Tiger.
It's just some suggestion
