Personally I always greet my opponent with Hello to you,hope you enjoy our game.(One opponent did reply in a foreign language he'd enjoy it more if I moved!)Then at the end of a game I thank them for the game & wish them luck in their other games.
why so unfriendly?

I was curious what people feel about greetings (good luck) and congratulations (after a loss) before and after games. I enjoy games being just slightly less anonymous, but I think that is just me being overy sensitive.
If you take this online stuff seriously, then you need to get a life.

Courtesy towards real (not virtual) people, whatever the circumstance, online or face to face, is worthwhile, seriously.

Quite so.

chessph,the phrase "get a life" is so imprecise as to be meaningless;the individual in question determines what consititutes their goal in life,not the observer.If the observer decides that an individuals actions doesn't constitute something of any real value that is fine,and also an utterly worthless judgement.Rudeness online usually translates to rudeness in RL(or a desire to be rude if in fact one can't actually get away with it).In fact,online behavior,far from being artificial,represnts a far more accurate assessment of someones real inner workings than RL interactions.People aren't"nice" in RL but jerks online,chances are,that the RL is the actual facade.
Scientific law - nuff said.
