Adium

Adium is a messenger that helps you talk to your friends and family over the internet using different messaging services like Facebook, Google Talk, and AIM. It's like having a phone that can call different people with different phone numbers, but Adium can talk to different people on different messaging services all at once! You can send messages, see when your friends are online, and even customize Adium with fun things like different chat themes and emoticons. It's a great way to stay connected with people even when you're not in the same place!
