I couldn't find this today, so now that I have, I'm blogging it so I'll always be able to find it. TNX Scribble is an online scratch-pad. It's good for when you want to talk about code over instant messaging. Typing code into the IM client usually smilifies it, garbling it. So you paste the code into Scribble, and it gives you a unique URL for it. Paste the URL into IM, and your friend can visit the URL to see it.
