Geek Tip: Find Out If Your Friends Click Your Links With LinkBlip

You know when you send your friends a link to this hilarious video they have to watch, and you have a sneaking suspicion they ignore your judgment on great links? Be a totally crafty (and possibly annoying) detective and catch them with LinkBlip. Go to LinkBlip's home page and enter your email address and the link you want, and LinkBlip will create a new link for you. This is what you send your friends — they click it and see whatever genius new viral video you've found. LinkBlip then sends you an email confirmation stating who clicked it. Absence of an email confirmation means, obviously, someone has left you hanging.

Then when they act like they've seen it, you can be all "nuh uh."
