Check out Devin's brand new app here : http://www.thescoutapp.com
Devin's chrome extension is very stable, simple, and functional. It also has a crisp ui feel to it. I was part of the closed beta group, and have had the extension on my chrome browser for over a week.
Devin just opened up Scout from a closed beta group to be available to others. Click through to the website and hit the "Upgrade Google" button.
I look forward to collaborating with Devin on future search related projects.
Enjoy and remember you heard it first on For Techies Only.
