Yahoo! Babel Fish
Though second to Google in popularity and many use it as an alternative, Babel Fish is far behind it in terms of accuracy and we were greatly disappointed. You can directly translate from the Yahoo! Toolbar (which could be useful to those who use Yahoo regularly), search the web using the translation results, and also allow users to translate your website by adding a widget. Even though the translations are powered by SYSTRAN, it doesn't have many languages to choose from (especially disappointing when it is considered the second popular translation tool) and finding the languages using the drop-down window is a lot to sort through. The language pairs do not exactly match each other either. The accuracy is terrible and among the worst.
