Ok, this is too awesome not to share... I know the description clearly states this usecase on the app page, but I figure most people skipped it like I did, thinking the Barcode Scanner is only useful for shopping etc...
You can send your droid urls without going through email/sms or anything, makes sense for youtube clips or any complicated urls you don't want to type:
save the below bookmarklet (FF or Chrome):
The Droid will recognize it as a URL and present you an option to navigate there!
