Interesting... , though I put this in the same class as SteemHunt, its not quite the same as the post can be edited after you use the ActiFit portal and more content and story can be added.
@bingbabe (my wife) is a compulsive runner but cant be bothered with Steemit. She did her second only post last week (with my help), which was an ActiFit one.
I added a load of pictures to it, some information about what happened, and a stalker report. As a lone woman she gets plenty of unwanted attention.
I think if enough info were to be added then the post could be viewed as to have some value.
You may want to assess Tasteem reviews (restaurant ones), in the same light.
They are a dApp, and the poster can make some easy rewards if its comprehensive, but is it really interesting as a reader?
I do these all the time, as I eat out regularly.
