The main thing for me is the cleaner UI. I like pastebin because of the syntax highlighting (doesn't support VDS however), and it keeps the source formatting (line indenting), but I like shrib.co because it's easier to edit and I can "archive" a version of a note and get back to it if needed. Pastebin does not have a feature like that. I keep backups of my versions, but that is a very convenient feature to have.
