Not yet, but in Reddit in recent years I mostly posted in niche little places for interests I didn't know there was a community for. I'm just hoping they will migrate or evolve over here because I found so many fun little hobbies because of the organic finding of new subs that Reddit seemed to foster.
And I have a 4mo old baby so that limits my time too. Every day though there is more and more, so I'm hoping I'll be a contributor to help it grow soon!
The Switch was announced in October and released in March and it was plenty of time for hype. A console with this many sales didn't need a year of hype, I think that long of a wait would do the opposite actually.
