I like both.Yahoo is a little cheaper since they don't charge a connection fee per call as Skype does. Both get the job done. Not a hell of a lot of difference.
I like Skype more than Yahoo messenger. Because its Skype has many interesting and useful features which attracts me much. Also there is the facility of video chatting. Its really very interesting.
I use Yahoo messenger it is a very good and old software for communication. Best software I ever use for video chatting.
Well we all know how Yahoo runs everything. They had the search engine many years before Google shows up and yet they lost the battle. They had the Yahoo messenger way before Skype was born, again the lost another battle. They had the Yahoo 360 way before Facebook too. Yahoo is the best in loosing, don't get us wrong Yahoo, we still like you since we can call you grandpa in the internet world.
