There are countless uses for an app like ICQ. Whether surfing the 'net with your friends, conducting a business meeting with employees located all around the world, collaborating on a book, or developing a Web site with your online partners, ICQ makes it all possible and offers you the ability to do so in more ways than ever before.
The only real downside is that unless your friends have already registered with the ICQ server, you won't be notified when they connect. So you might want to take my advice -- rush out and get all your friends signed up so that you can begin taking advantage of this extraordinary client today!
Pros: Tons of features, continually scans the 'net for your friends and acquaintances
Cons: Must first register with an ICQ server, external apps needed for some tasks
