I have no idea. I think it helps to have followers. Whenever I put up a new listing, I share it with my followers and a lot of them share it too. I hope that gets me more exposure that could result in sales. I don't think following others is going to benefit me but sometimes I follow people who follow me to be courteous.
You can filter your news to one category, such as likes or offers, but you can't filter to see more than one category at once, and you can't filter out things you don't want to see. There is one item I liked a long time ago that gets auctioned several times a day.
