Re: Facebook for news
The problem with having "trending" topics based on what my friends are reading on Facebook is that I have a variety of friends and don't always share common interests with them. But I do think Facebook can still be a good news source. You must be proactive though. When you follow pubs and websites on FB that are important to you (NYTimes, Wash Post etc), your FB news feed can become a good resource. I've designed it this way, de-emphasizing (hiding) friends and emphasizing news and media. I've discovered a lot of great content this way. I keep friends around who share my interest in news and media (with the hope that they will post interesting content). But I've admittedly hidden friends who post fluff.
