Guys, in all honesty right now the webrep doesn't bring much to the table as any simple community based reputational tool like this is subject to poor info from less than knowledgeable user input. Don't tale any reputational tool on blind trust, at best they are a guide only. So until we start to see input on this from the virus labs on actual malware detections it isn't a security enhancement.
That said the fact that it is new as is the background infrastructure, the servers retaining the data, etc. are getting overloaded and will at times not be available, this will take a little time to get the balance right.
So if it isn't available it isn't the end of the world, you are no less secure.
