To me, answerhub always felt like dead wasteland, so I will be happy to see it finally gone and the community stop being fractured between two websites.
Whenever I came to answerhub, I often saw some ancient relics of conversations where actual Epic employees answered with very valuable information. Occasionally even Tim himself. But that ended around 2015 when the popularity of UE4 exploded and Epic staff simply did not have enough time and resources to contribute anymore.
After that, it’s just became mostly depressing corner of either high quality questions with no answers, or low quality questions with low quality answers. The fact that the website is ultra slow, and that the layout is chaotic and clunky by today’s standards doesn’t really help it much either.
