IM is worth paying for. People just aren't paying for it right now because it is FREE. And they will use whatever is FREE. Well not the people who pay the $25 a month for the AOL ISP, they will pay for anything if someone pushes it enough. But everyone else will use whatever program is free. When MSN/AIM/and ICQ all go to a $3/month or whatever it is they are going to charge for it, a few new players will emerge (if there is money in actually doing it for free) that will be free and half of the free thinkers will use the new programs. The other half will pay the $3.
