I am 100% self taught in all programming languages that I know. (Whoopie for me...) Anyway I am having a tough time figuring out how to push updates. For example if you are reading a Yahoo story that allows posting of comments, you can be reading the comments and as new comments are added, they are pushed to you without you refreshing the page. I have no idea how they do this, if it is a language specific trick or what. Can someone please point me to a primer on how to do a simple version of this?

I know that you can update pages dynamically with AJAX.
I've done it once. But completely unrelated to this, so that won't help you much.
The function to check, you could call every X seconds.
That is all in theory. I don't know where to find info for that

lottos ... Looks interesting! Thanks for sharing
