I use Skype and trillian web messenger. Trillian can allow me 2 gtalk ID, yahoo, Hotmail and much more in same time.
Yahoo Messenger was famous around 5 years ago and even I used it most of the time. Although not any more. Mostly Skype these day.
For basic use Whatsapp is best and other way for live video conversation skype is most useful and best messenger
I usually use whatsapp messenger through mobile for chat & sending pictures, its a fast app to work for these type of works. Further i also installed viber for voice calling & skype for video chat. There are few more Tango sometimes i use for social networking for making friends online for chat. thanks
I use Skype, Google Hangouts, and Viber. I used to have Yahoo Messenger but not anymore. I also use Facebook Messenger but mostly for personal purposes.
I. HATE. SKYPE. But I use it! I loved Yahoo messenger, but for some reason everybody acted like it's so NON professional. :X :-* .. can't imagine why :$ >
I use Telegram and Skype, but at the moment I don't have confidence in the security of each of them. Each of these messengers has advantages and disadvantages. I really want to use the perfect messenger)))
