Web applications like Gmail, Facebook, Campfire and Pandora are becoming more and more like desktop applications every day. Running each of these web apps in a separate tab in your browser can be a real pain. Even if you use Google Chrome Extensions ;-). Along comes "Fluid".
Fluid lets you create a Real Mac App (or "Fluid App") out of any website or web application, effectively turning your favorite web apps into OS X desktop apps. Sounds great ... IS amazing! Checkout this vid:
Fluid is free. You can download Fluid for free and create as many Fluid Apps as you like.
