I can attest that this is a pretty significant update. I'm seeing sites like cPanel/Plesk/HestiaCP resurface for server related queries, which is pretty dumb considering that these are control panels and most of the time borrow content from Stack Exchange anyway.
Is it against Reddit's terms of service to use a sub-reddit as a blog? Because I think that's the future with how Google favors Reddit/Quora and other UGC sites.
