Reading that full article was a bit scary... this sounds like a perfect way to get already popular items even more time in the spotlight... I'm pretty sure buyers will like it, but I don't see how this is good for all authors. Where's a proper search function with useful filters?
Hey sightsignal, that's definitely not our intention with his feature. We appreciate the concerns that authors have about getting exposure to their new items, and Trending, among others, is an attempt to get more exposure to items that have had a little bit of interest and are just beginning their climb towards popularity, rather than rewarding just the items that are already at the top of the tree. We're still tweaking the knobs, and will be continuing to do so over the next few weeks, to make sure that this is actually being reflected.
With regard to your wishes for additional functionality around search, I can't say too much but I think you'll be pleased with some additional releases we'll be making in the not too distant future.
