I get what you mean, but I think that the problem with the usage of photos can be brought if you're having a photography post, where the picture gets all the attention. In a writing post, I don't think is such a big problem since all the focus is on the writing.
Also, take into consideration that most of the people using Steem are not bloggers as a background thus they have no idea about things like this. They are probably just trying to fill the gaps in a large writing post like I just did. :D
