I can see how the logic around this went: There have been some negative press from folks who worked on the trending team which probably pissed Facebook off. Theoretically, clicking on a trending topic would bring up the latest news articles posted and provide additional information/context.
The reality is that I am seeing a lot more tabloid-esque topics that seem like they might be relevant but are not once I click through.
Yesterday, a trending topic for me was #mcchicken which I thought oh maybe McDonald's released a new chicken sandwich or some type of food/health news. Instead, it was trending because some guy basically stuck his penis in a mcchicken sandwich and posted a video of it. Previously, I would have expected human editors to either deem this unnewsworthy or at least provide a better one word description than #mcchicken maybe like #guyhassexwithmcchicken.
Anyways, I'm sure it will get better over time but I am missing the old module. I thought the descriptions were succinct and well written.
