Does anyone have a clue about how blogs are selected to be at the top of Facebook's trending tags? There's always one blog at the top that is given a position over the others, it usually isn't a major network's blog or news site's blog. It obviously isn't share or like count, it just seems to be random... Maybe something to do with velocity? Maybe it's hand picked? Anyone tried hard to reach that top spot before? It must bring in massive traffic.
