Fellow Adobe Platform Evangelist (and recent ColdFusion devotee) Greg Wilson has created tBlurb.com, an app that lets you enter code and get a short URL to it for sharing (you can choose your own or let it pick it for you). The app features a rich text editor, and supports ActionScript, C++, C#, ColdFusion, CSS, Delphi, Java, JavaScript, PHP, Python, Ruby, SQL, VB.NET and XML/HTML. And Greg built it all in ColdFusion!
The code isn't syntactically highlighted until you save it and then view the page but it's really nice when you do with line numbers included:

Anybody got any original Farrah posters laying around they don't want?
