Quora had heckloads of users before the well-working topic system was destroyed with the excuse of tag spamming (real reason: cost-cutting), which us tedium-loving "Topic Gnomes" had always corrected quickly. So it's not impossible. Now the tagging is done badly by "AI" and my feed content went to shit, even worse than on PieFed with a leaky keyword mute list.

Missing features were a trust system for topic editors (new user = 0 trust, etc.) and answer topic tagging - only the questions were tagged, which didn't work when the question was general, like "What should you know in 2025?" and the specific answers were all over the place.

Keywords would never have worked for the infinite questions about perpetual motion machines, because the askers never knew the correct term. Similarly, I have failed to craft a keyword block list to filter out all U.S. politics.
