I have had a look at the new features at Pubsub and found that even though they have done a great job in detailing incoming and outgoing links they are missing large chunks of data. I did some link counting on my own and they are missing a large percentage of the outgoing and missing many of the incoming. I am not surprised but until a service can scale big enough to make sure that they are not missing anything their will be holes. [Pubsub Linkranks LinkCounts and SiteStats]
Oh and another thing most of their feeds are ATOM the question is were are all of the RSS feeds. This is a site wide issue. People are already confused enough when it comes to RSS and yet they have everything listed in RSS. They also promoting something called SB Enhanced which I have never heard of?
