Great question! Think of it as going to a party. People tend to gravitate towards the guy or gal who has interesting things to share and is able to convey them in an engaging way.
S/he could be talking about Indian motorcycles for twenty minutes and people are eagerly listening and asking genuine questions, even though they came to the party with zero interest in motorcycles. Then the guy/gal talks for thirty minutes about hiking the Appalachian trail and the same thing happens.
One of my favorite plugins for Firefox was Stumbleupon. It often shared intriguing stuff that you had no idea you were interested in. Your Featured timeline definitely brings back much of that joy, but following great conversationalists allows me to personalize and create my own “Featured Conversations.”
Does that make sense? I have no idea if the above is shared by only me, or if it’s antithetical to @Julianne’s evolving viewpoint over the past three weeks of what Cake is/should be
, but it is something that is akin to following a blog commenter over multiple blogs.
