I've no idea if this has been around for awhile or not but Crime Mapping is new to me - a perfect blend of a pleasant map interface and geolocated crime reports. It's nice to see what crimes may be happening around your home / work and ramp up your Fear Meter in case you feel like they're slowly closing in on you. I'm actually sort of shocked at the number of "Fraud" incidents in my general area - lots of trickery going on!
