One more time my friend Kreg Stepee from the Techorama podcast turns me on to one killer application. Fluid

This is not a maybe get this application. If you have Leopard (required) you must get this application and use it.

Fluid itself is a very small application. When launched, Fluid displays a small window where you specify the URL of a webapp you’d like to run in a Site Specific Browser. Provide an application name, click ‘Create’ and you’ll be prompted to launch the new native Mac app you’ve just created.

I’ve already used it with Seesmic (even made a short screencast for them during lunch) and tried it with GMail. Go see for yourself and then show some love for the developer of Fluid .
