Fresh Links! Delicious!
Just what I needed! Our library has quite a large collection of links on Del.icio.us, which I have been worried about doing link checking on. But never fear! Here comes Fresh Del.icio.us, a link checker specifically for Del.icio.us.
Remember, just like any link checker, you don't want to start this in the last few minutes of your workday. It will need some time to check through your links. The more links, the more time. I start them early in the day, forget about them and then am pleasantly surprised that they are finished in the last few minutes of my day.
