Late last week 
MySpace launched their very own instant messenger, MySpaceIM.
At first you could be mistaken for thinking the IM market is really heating up in the competition stakes! But really, is it? Of all the current IM applications, none of them have interoperability. So to keep in touch with 
all of your friends online you need to use, MSN Messenger (now 
Windows Live Messenger), Yahoo! Messenger, AIM, ICQ, Google Talk, Skype, and now 
MySpaceIM.Yahoo and MSN gave us this little 
teaser to join forces by the first half of 2006, though they don't seem to be promoting that venture anymore.
So tell us, what is your favorite Instant Messenger and why?
