I've been steadily sinking deeper into Go (the board game, not the PL) for the last few years. I keep thinking that my enthusiasm for it will dry up soon, but it just keeps increasing. The depth is immense, every few months I feel like I'm swimming along the bottom of the ocean, then I come to a continental shelf and as I stare into the depths below, I realize that I've only explored the shallows, I dive, and leave the surface behind even further.
