"Site Specific Browsers (SSBs) provide a great solution for your WebApp woes. Using Fluid, you can create SSBs to run each of your favorite WebApps as a separate Cocoa desktop application. Fluid gives any WebApp a home on your Mac OS X desktop complete with Dock icon, standard menu bar, logical separation from your other web browsing activity, and many, many other goodies."
