My dad was an artist and a person could look at his paintings and think or feel something. But looking at them with my dad standing there also, talking about his work, provides a my h deeper level of interest and understanding. So, yep, I get what you're saying. I don't mind that many just scroll pictures on my posts, the writing is primarily for myself and my own enjoyment. Sometimes I wish people read though, they may find something of interest if they took the time to do so.
I think your tutorial post sounds like a good idea and could be a fun post for you to put together. Fun is the key here I think, so anything that provides it is a good thing.
I'll look out for that other user you mentioned and...hopefully "my reputation" isn't all bad. Lol.
