You might have noticed we added "categories" today. Over time, "topics" became more like keywords rather than useful for goal-directed searches within specific product verticals (which is most PH searches). Categories will help us improve search and browsing, as well as eventually a lot of other downstream features. Ex. Zoom *is* video conferencing software, not "tech, productivity, video, SDK, meetings" Categories are what your product is or what problem it solves. Topics might include general industries, specific features, technologies, or keywords. At the moment, categories are meant to supplement topics. Topics will still exist, although you can think of them more as ‘tags’ than a primary taxonomy. We built out the a lot of this from scratch, so please suggest verticals we're missing – if your product isn't categorized yet you can do so by editing your hub page. Lmk if you have any questions!
