I must have missed any announcements about this new feature but recently noticed the Impact Metrics area posted to all threads. I generally like this new feature and look forward to exploring it more. Many other public forums that I participate in have some kind of a participation metric on it similar to this.
If anyone has any more information on how the Impact Metrics work I'd be interested to know the difference between the Views and the Viewers stat. Those two sound similar to me but perhaps one is how many unique visitors have clicked on a page versus how many times that page has been opened? Seems like they may be a little skewed since many threads have a high number of views but often a low amount of viewers. The rest of the stats are self explanatory.
'Views' represents the number of discussion views whereas 'Viewers' list the actual member names of who visited the discussion. 'Views' aren't unique, if you reload the same discussion twice - it counts as two views.
