Social platforms now let users declare topics in plain language, changing how posts get matched

Over the past year, Instagram, Facebook, Threads, YouTube, and TikTok have each added features letting users type the content they want in their own words. The author argues this shifts recommendation away from purely inferred behavior toward explicit requests that posts must match. A declared topic is treated as a strong signal, so posts whose subject can only be described in jargon may be excluded from matching. The author notes platforms have not disclosed how much weight declared preferences carry or how many users actually use them. The piece suggests creators name their topics the way audiences would, in a single clear topic per post.
