Have you noticed recently that your Rails-related API searches on google no longer display links to the old Rails 2 API documentation? Tired of changing the TLD from api. to rails. just to view the older documentation?
Drag this: r2b to your browser toolbar to add a simple bookmarklet that you can click while viewing a Rails 3.x documentation page. Go from red to blue!
