g talk vs yahoo messenger

according to me i am telling that both are best in there position as in yahoo messenger you have to make your account in yahoo ,...\ yahoo messenger is so wide as in this you can talk with whole world as even in america as well as in whole world any where as there is a chat room where you find who is in online and it is also user friendly as every can use this easily .. in g talk you have to make a account in the gmail and you cant make gmail account without any invetation as this problem is not in the yahoo mail . as in g talk you can talk with that one who is join in your g mail and you cant talk with whole world only that one who is join in you so according to me yahoo mailo is the best one ..............

yahoo msg anytime ...

Actually yahoo messenger is better, cause that's what most of the people used. Infact, only few knew about g talk, you see the difference. Thanks.
