Who gets priority in your Facebook timeline?

Join Yahoo! News, led by columnists Virginia Heffernan and Rob Walker, as we discuss the recent controversy over how Facebook determines what appears in your timeline. As The New York Times wrote over the weekend, simply sharing articles or content with friends or subscribers is no longer a guarantee that they'll see it. Using Facebook advertising, however, which one must pay for, ensures many more eyeballs. Is Facebook merely being greedy? And what does this mean for average users and what they can expect to find in their feeds?

We'll discuss our own experiences with sharing content on Facebook, and take your questions and comments about what deserves to appear in your social stream.
