First impression from the Facebook chat is that it’s just another chat to use. I never saw any difference in the Facebook chat, than the MSN and Gmail Talk one. Chat is chat, you say a word and get the reply in seconds. This is the whole big thing in the instant messaging, so what the big deal with Facebook chat?
I will tell you what it is all about, the Facebook chat smiley and the Facebook chat emoticons are the big thing to use, while chatting online, forget about the old fashion chat systems, the new opportunity to use the Facebook chat smileys is the new way to chat. The new features from Facebook, the new items to use, the new design for the accounts and group, these are all part of the great experience from Facebook
Since there are too many Facebook chat smiley emoticons to use online, the best way to get to know them is to start using. Look for the ones you like, use them while chatting, learn to know the new ones, using by your chat friends and use them too. Still, there are some famous ones, listed here:

Don’t use the Facebook chat if you are not going to use the smileys while chatting. One smiley can say in simple way, the thing you like to say in 10 words. If you are young enough and smart enough to use the Facebook chat smileys online, you can have full conversation, using emoticons only.
