Teachers: Run your own HomeworkMatters site designed specifically for posting homework and other class information.
Open source project – bookmarklets and user scripts that translate real-time social network user-generated language content in sites such as Facebook and FriendFeed (uses the Google Translate API).
A bookmarklet and greasemonkey script that translates friendfeed posts and comments from one language to another (e.g. Farsi to English, German to French, English to Simplified Chinese, etc). Source language of each entry/comment is auto-detected and converted to chosen destination language.
A greasemonkey script that on mouse hover, long FriendFeed comments are revealed (avoids needing to click the “more…” link. Only tested on beta.friendfeed.com). Installer available at http://userscripts.org/scripts/show/47724
