Keep Hearing About Ares for File Sharing

My friends are all a bit ahead of me when it comes to technology and the Internet. They know what is cool before I ever even hear about it. But I listen to them and try to pick up things from them. I keep hearing them talk about ares. They have mentioned some of the cool things that they have found on there and some of the files that they have been able to share by using it. I think that I am going to look into it and see if it is something that I might be interested in using as well.
