I have used Skype more than yahoo messenger. I have found Skype handy but I feel Yahoo messenger is lighter than Skype.
I personally use skype and it is much more better than Yahoo... But in some cases yahoo leads like in mailing and other but skype is good for chating and sharing small files instantly
if you chat i think you should using ym but if you wanto send file and chat group then you should using skype
well both are good , but i think skype is more cool ,bur it is slower then yahoo because it is heavy , regards,
I use skype to talk with my mom & YM to chat with school friends but still skype has better sound quality in my opinion
Obviously skype, YM is filled with bots adding you and then flooding you with spams. Skype is clean, only uses one window, unlike that of YM's.
