Sometimes when I'm bored and messing around with my phone, I check out "Trending Threads". I assumed that threads made it to this list based on an algorithm driven by variables such as new activity, recent velocity, total replies/views, etc....and, that is more interesting to me than the catch-all "new posts".
But, today it dawned on me that the trending threads I see are about 60% BA, 20% DL, and 15% TB, UA, AA.
While I do find the BA forum to be among the most interesting/engaging of the lot, some of the BA threads that make it to the trending list are about really mundane topics (e.g. lounges in Nashville). Meanwhile, during casual browsing, I often come across threads that aren't considered trending in other forums that are kind of interesting.
