Hmm that’s interesting.
It would be really cool if the user could specific the lookback period. So users could see which tags are popular now vs a week ago vs the past month/year vs all time.
You might be interested in creating a post that is perennially high paying even though there might be a current dip for whatever reason (seasonal, fad, etc).
Sort of like a google trends view
all of our reports will be available for historical recalls until we are able to build a front end to display it. Guess that's the manually way for now for ppl interested. Don't tell anyone, but we also own the "@SteemTrends" account and have ambitious goals of releasing exactly what you mention. ;) This project has gotten a bit larger than I had originally expected and we may be looking for another dev.
