i use gmail, skype, ymail, facebook... hahaa but, i love to use ymail... free for video chat than skype... facebook better than ymail, i think... playing game and video chating...
Skype is way better than yahoo messenger i think, it is lighter, faster and attractive to use. I always contact with my friends and close one's using Skype.
Yahoo messenger is good to keep a track of all incoming mails to your inbox. For calling and video chatting, skype is best.bt also i use skype more than yahoo messenger.
yahoo is older one while skype one of best updated software, and better than yahoo. i used skype now.
I have used both messenger. Skype is better then yahoo because we can transfer large amount of data and files through Skype, and there is an option to rectify your sent message.
Skype is the stone cold nuts. saves conversations from place to place etc. its really stable for me. dont lose anything.
