It would seem this has become so.
The idea for this for forum is relieve some of the randomness burdening the general forum. There had Ben a lot of complaints about things that "didn't belong" in general in their opinion, and many people have their own opinions about pull-posting as well. This forum was made so that these types of posts have a place to go without bothering anyone that doesn't like them in general chat.
General chat is still for talking about magic and just chatting in general.
Fun stuff is for forum games, fun little quirks like polls and lists of "top 5's" and all that, as it always had been.
Pulls and ponies is for random, non-mtg stuff that just doesn't fit into general or fun stuff. And pull-posting.
This is my understanding of it after having discussed it briefly with Piotr and a couple other mods. I'll admit I didnt get it either at first, but its kind of nice now that these posts have their own home.
It needs a new name though...
Nothing against pulls (or ponies) but seems its a lot more going on.
"Blabber channel"
Or maybe just "Random"
Btw with this up i think some of the "videogame" sections of digital could be moved.
