MSN is the best IM - all the other ones are so damned nasty, they look like they've been made in Visual Basic by a Child - obviously the programming is reasonable, but the style can be easily copied by a child in Visual Basic 6.0. MSN is the only one available that actually looks like a Messenger.
Google IM... few words can represent the vile congealed evil represented by those six colourful letters.
A Knight is sworn to Honour. His heart knows only Virtue. His blade defends the helpless. His might upholds the Weak. His word speaks only truth. His wrath undoes the Wicked.
