I feel this is true.

I am now posting a story exclusively on Steem, this is already part IV and there are three more parts linked inside:

As for my photos, though, that's my job and they have to be everywhere possible. Some tutorials and articles can be exclusive here and have been so far, but the images themselves — that I cannot do. For understandable reasons, I believe. What can be exlusive is the context I use them in (and it's mostly so).
