Kind of a far off idea of mine that I'm trying to imagine parameters for. I'm wondering if a program like Adium can be built -- but instead of people being able to chat with you, it gives you an MSN-type notification every time someone posts in a thread you're involved in online. So like, people can "subscribe" to certain threads that they want realtime notifications on every time a new post is made. Done in a package that sits nicely on the desktop in an unobtrusive way that is handy to use. My idea is that this kind of software could really enhance forum traffic on certain boards and would probably be quite useful if it can realistically be developed.
