Idk about you guys, but this makes me VERY happy 
Especially since (after testing) my instance ranks incredibly well. Could this revive discussion forums around the globe? I remember when Google killed the filter years ago, those were bad times.
EDIT: So far seen in Poland and United States, I am not sure if this is a test or full roll out, but Google is updating the core. The Forum tab literally popped up ten minutes ago while I was searching for something.
