Hi there. I think it'd be great to have a section near the top of the main page that shows what are the trending topics users are talking about in XMB.

For instance, if users are talking about "Britney Grammy's" - that'd be one of the key terms showing on the main page.

In other words, whatever phrases are being used the most (like Twitter) - it'd show up at the top! Users can ban together to get Trending Topics on the main page. Very fun and interactive idea
