I mostly play on Tygem, and I understand it has a slightly different mentality than KGS for example, but if you want fast games, then why accept longer time settings? And even if taking into account the sandbaggery, what satisfaction could one get from playing against a clearly inferior opponent you don't even need to think against to win? GO is confusing but, damn, people are even more so.
Maybe it is something people expect there, to be quick, but it just doesn't seem beneficial to actually becoming a better player IMO. Seems such a waste to see thousands upon thousands of people online in there, and the majority of them are in a horrible hurry. I don't understand the mentality, for I believe if something is worth doing, it is worth doing well enough to actually improve yourself. Actually, I don't really understand blitz games at all, but maybe I am a slowpoke mentally, and surrounded by superior humans.
