One of our most requested features has been to add some cool smileys/emotes to social.im, so here they are!
Upgrade to the latest version from http://social.im (or Check for Updates on your client) to get smiley feature.
Click on the grey smiley icon to see a list of possible smileys. Some are available immediately while others you'll need to be unlock by inviting friends.
We've added some cool and some pretty ridiculous emotes, so be sure to check out the whole list!
Also, you can even earn the right to upload an image of your choice as an emote. Check out http://apps.facebook.com/socialim/emotes.php for more details. Impress your friends with a custom emoticon that only you can send!
