Protopage is an RSS reader, virtual desktop, and Internet start page launched in London, United Kingdom, on 15 May 2005. The design offers color-coded tabs and categories to organize information, an audio and video podcast function, a news reader, the option to add cartoons, and a selection of widgets, which can be dragged onto the desktop, arranged, and re-sized. It is highly customizable and has been described as "simple to use." One criticism is that it has only one mail widget, which requires connection via IMAP.
