Pasterly is a paste bin site I made because I couldn't find any that did it quite right. It generates a snippet URL as you type, and uses the ACE code editor to provide IDE-quality code editing on the fly. I don't think either of these things are that big of a deal, but I didn't see anyone else doing it. Please give it a try and tell me what you think! There's plenty of things to do before it's full-featured, so be sure to tell me what you want to see first. It's sort of my own little weekend UX experiment. The source is available here if you'd care to browse it, report bugs, or request features.
Since this uses the browser-based ACE editor, syntax highlighters for some systems languages (*cough* C *cough*) are missing.
