Not sure which post you're referring to, but maybe the original over a year and a half ago?
As to "where" I'd have to say "the internet." There are so many different communication platforms now, it's hard to keep track (bitcointalk, twitter, facebook, discord, telegram, slack, etc, etc).
What has changed? We're still here. That and the underlying blockchain and interfaces (steemit, busy, chainbb) have improved.
As to what it needs to take off? That's too big of a question to even give a general answer. Any answer given would be incomplete, misleading, and potentially invalid within a very short time. I've given answers in the steemit growth forum and on the panel discussion I was on recently. Maybe this post gives some of the answer.
