If you aren't using it yet, you have to try it.
This is a great piece of information design. I've been checking it regularly for the last two weeks or so, and I find that I pick up news that would have previously completely passed me by. This is because buzztracker draws your attention to the most
significant (from the press's point of view) news, whereas on traditional, headline-based news sites you are most likely to notice news associated with regions or topics familiar to you.
I only wish the article titles weren't truncated.
Also check out the
About page, which is quite interesting.
