Quoting from dashLicious:
dashLicious is a Dashboard widget that “implements a post to your del.icio.us account on the fabulous web service created by Joshua Schachter. dashLicious is optimised for Safari and NetNewsWire users. When you enter into the dashboard dashLicious will automatically populate the url and description fields from either Safari or NetNewsWire (and will allow you to toggle between the two inputs).”
I’m waiting for the early adopters to kick the tires on Tiger, but stuff like this is making me drool.
