Was there a clear point where TAGS emerged as a distinct concept to you or was it a more gradual movement from the "subject" days? I read Maciej's account of ingesting A03s giant tag ecosystem in which he quotes you calling tags "a reverse search engine." That stuck with me as an insight that doesn't come up as much in a world where we take tags for granted. Curious how you got from Memepool to there.
