I’ve just started using Fargo, a new browser-based outliner from Small Picture. This little tool is platform-independent and works within any modern browser (i.e. Chrome, Safari, Firefox, IE10). It’s an HTML5 app written with JavaScript. Files are stored in Dropbox in an open format (OPML).
Why use this instead of one of the myriad of other outliner tools on the market? It's simple to use. You don't need to install proprietary software. It's available anywhere you happen to need it. You don't need to worry about 'lock-in.' There's no need to export your files, ever. It's free. It works well. I like it.
