Skype might be baked into Windows 8.1, but let’s be honest: Instant messaging is a fragmented mess. Some of your pals may use Skype, but vast hordes rely on Facebook Messenger; still others may use ICQ; and tons of folks still use AIM, Yahoo Messenger, or other alternatives. What’s a well-connected PC geek to do?
Simple: Install Trillian, a chat client that supports all those services and more. You’ll never miss a conversation again, no matter which IM clients your buddies prefer. (Bonus: Trillian offers iOS and Android apps, too.)
