The nightmare of a system like this is aggregating data from multiple sources. How would you pull and combine viewer & reader data from hive.blog, PeakD.com, eCency, Dapplr, 3Speak, Vimm, WordPress blogs using the SteemPress plugin, etc. etc. I just don’t think it’s feasible to automatically measure attention at the front end levels in a way that distributes blockchain level inflation.
