I think Go has many qualities which should attract the SC player. Just like SC, it is easy to learn but hard to master. It appeals to those who are relentlessly competitive and seek improvement in what they do. And lastly, Koreans tend to be cho-gosu and have a similarly feared reputation in both games. Its also been said that a lot of the top Korean and Chinese players are more than casual players of SC /WC3 - apparently in a tournament within the last couple months in Korea a lot of the Chinese pros went to play SC at a PC bang in their spare time.
Here are some resources to learn more about Go:
The Interactive Way to Go -
Easy tutorial to learn the rules. Recommended if you are a complete beginner who wants to get into the game.
A community maintained wikipedia. A great resource for learning about specific moves, history, or just common go terms.
This used to be one of the focal points of the community. As of long, it is supplanted by the Life in 19x19 forum (listed below) as the owner no longer had time to maintain the site, which was suffering from chronic technical issues. However, its archives are still a treasure trove of information.
Life in 19x19 Forums
The replacement forum for Godiscussions forums. Most of the veteran members have transfered to here.
KGS Go Server
Great free server to play online go. Very newbie friendly with good community atmosphere , with lots of stronger players willing to help out. There is already a teamliquid room there, but its rather sparsely populated right now. To join go to the Rooms -> Social -> teamliquid.
Great site for free life and death problems.
If any TLers already play go or wish to learn more about the game, feel free to PM me or ask me for a game on KGS. I'm Aphelion02 on KGS and am 6k in rank, which is by no means good, but it would be nice to play with a fellow SC fan in Go.
