It was made to compete with google. They use different techonolgy but copied the clean simple interface. It's for people that don't want the full portal experience. It hasn't caught on yet, and I have doubts if it will ever be a hit with the mainstream.

There was (is?) a slight difference in the database. I've had sites that change position slightly between the two. If Raging is going to die, I hope they just keep the interface and point it to the AV database.
