Who needs multiple instant messenger programs?

Out of all the things i do on the computer Instant messaging is a must because i have so many contacts throughout many huge companies i can not risk losing contact.
So i turned to Microsoft again to see what they had to offer, I found a messenger client called Windows Live Messenger (WLM).
This is truly a great program from Microsoft, it has a great 3d looking glossy GUI environment and a huge list of features.
Also the ability to add not only Microsoft users, but MSN and Yahoo messenger users also, now thats spiffy!.
You also have a choice in the display picture selector to select something like a WEEMEE (an animated avatar made to look just like you, with emotions and sound too!), thats a sweet feature i must add.
Go check it out, i doubt you will ever go back to MSN or Yahoo messengers after using Windows Live Messenger, Get it free at http://get.live.com/messenger
