Is art supported and if by whom? Are there steemcurators for Art/Artists only?

There are no curators exclusively for a single topic; it all depends on the curator's taste or the person managing the accounts. However, there are other factors that can be considered. For example, some users only share a drawing or a micro-story and talk very little about it; most curators take that into account.

You are both right: everything is supported! Does that mean everything is good or everyone can write and everyone has something good to offer? Does making artists look bad give Steemit a good name?

Nobody is looking to make anyone look bad, much less artists. The support programs are managed by the users themselves. Perhaps you can apply to be a curator and express your preference or criteria for supporting content.

Is the greatness of Steemit the most attractive thing: posting a few words, copying and pasting, translating, and receiving a good reward? Does understanding, telling yourself "Steemit is a great platform," make up for whatever's going on? What a strange approach, @adeljose.
I'm glad I don't rely on rewards or favoritism when posting. What you're promoting is buying votes, but not once you say "let's join forces."

Perhaps you misunderstood my words, or the translator didn't allow me to express myself properly. When I said "great," I meant it's very broad—more than 1,000 users, 500 posts a day, to give you an idea. Each user and each post has a unique characteristic. There are users who invest in Steem Power, and they have full rights to how they use their investments. I don't promote this; it's a strategy some investors practice to improve their earnings.
