Agree it's more fun without the elo anxiety. Personally 3+0 blitz hits the spot for me, everyone sucks so dropping a piece isnt a big deal. The popular advice is that blitz won't improve your game, but I don't buy it.
I play longer games to try and improve, and 5+0 or shorter when I just want to move the pieces to entertain myself. It's pretty noticeable in my rating too, haha.
