If you are one of those people that are crazy about the last little extra kilobyte of space on your hard drive, then this is the tip for you. Most people know that in Automator, you can save your project as a workflow or as an application (assuming you're not making it a plug-in). Applications work with a double-click, but workflows must be opened and run from Automator, which takes both time and CPU. Applications, however, take up more drive space than workflows. Here's how to get the best of both worlds.
In the Save As dialog in Automator, save your project as an Application. Back in the Finder, Control-click on the newly-creatd application and pick Show Package Contents from the pop-up menu. Open the Contents folder, and inside there is a file called document.wflow. Drag this file to your desired destination and delete the original application. Now you have a small file -- like a workflow -- but one that can be run with a double-click, like an application.
[robg adds: I tried this, and it worked as described. My simple two-step workflow was 384KB when saved as an application, but only 12KB when I extracted the workflow. There are probably a few downsides to this approach, though I'm not sure what they might be -- so comment away!]
