Ah that does sound like a dud business wise. It would be nice to see more extensive stats for each site I use, like digg, forums, HN, etc.. but most sites and users could do without it. The user won't be paying for these stats, so the site owner needs to benefit a lot for the hassle. These stats are being collected one way or another but there is a lot of variation from one site to the next. Could it turn into a big hassle for some sites?

A site owner might put extensive stats to use to design a better community site. You could make some summary visualization of the user into their profile icon, so others know who they're dealing with. Sites like digg, quora, HN already have a lot of stats on individual users and it wouldn't be a big deal for them to create a visualization for a user. More recent companies like Etsy probably have some sales stats users can see. It's a small feature on many sites, most users don't need super detailed analytics.

Too many stats are confusing, many users who use 3rd party sites like ebay, etsy, don't want the hassle of what site owners go through, like looking at referrers. Some simplified online popularity graph might get adopted by site owners, but many users won't even understand that.

With that said, developing the idea itself further wouldn't hurt. I'm sure there are more market fits for analytics. An analytics social network where people compare their stats to their friends seems like a pre-requisite for this idea. Otherwise 'normal people' won't understand what the stats mean, there won't be a competitive or psychological incentive.
