The I.M. world is growing, but with I.M. users unable to easily communicate with other networks it is a real problem. AIM is is popular with kids & teens, and is flashy, but really is just a stripped down ICQ with lost of pretty colors and cartoons but without ICQs power. Yahoo is very solid and works well but is also dumbed down a bit for their biggest market (kids). As more adults begin to find IMs useful the technology will evolve and become more useful.... but for now we suffer.
