I love Skype, its great just for catching up with friends or getting a group together to talk business , i wouldnt be with out it!
I use Yahoo! for mail and chatting. As it sync with my msn users. I use skype when required another chatting windows or call.
Definitely Skype is a lot more reliable than Yahoo. Skype is also well ahead with features, and is also much more advanced in terms of VoIP calling.
Skype is better for voice and video chat. It does have problems like slow time delivering msgs but it's real good. I have to go with skype. -Chaldo
I use both,but i guess that skype is slighly better due to the fact that they have a dedicated service rather than yahoo who offer many services,i do like yahoo email.
skype is better in terms of communication , but in over all i vote for yahoo , skype has good voice communication.
I feel comfort with Skype for voice chat and video chat, but for file transferring and text catting gtalk is best to me. I do not like yahoo; it seems clumsy to me.
