ISC Malicious Site database

From the ISC Diary:
They have created a webform for people to use to submit malicious urls. The submitted site will be checked, and if malicious it will be added to a database of known attackers. The site will also be monitored for changes.
Is this going to be a poor man’s antivirus system or a poor man’s websense? I guess its hard to remember that some people have to scrape by without the appropriate commercial tools. Blacklists are always reactive. At least in this case false positives should be avoidable.
