via codeboaz: Cool piping plug-in for Firefox. User highlights text and types in natural language phrases like "map this", which brings up a map you can insert into your email. If you select a bunch of text with links, it will crawl the links and parse them for microformats, for example you can use it to map a bunch of Craigslist listings. Browsers and operating systems need more powerful piping gestures, including piping feeds. This is a cool start.
