I learned Go 12 years ago. Until now, I've played so little that I've never gotten any stronger than about 14kyu. I teach all of my kids when they're very young and Hikaru has really piqued their interest.
Their interest is causing me to get interested again. I've been playing as Solap on IGS.
If anyone enjoys commenting games and helping folks improve, please let me know!
You should check out the Go Teaching Ladder. You can submit games for comment by stronger players and you can contribute by doing the same for weaker players.
