One of the reasons I like steemit is that it is both challenging the commenter and the poster to be creative at the same time.

I once saw a beautiful photography, I was about to type in "nice shot" when i saw i was entering the spamming territory, I had to take a look again at the photography and write about the colors, highlights and things I loved about it.

Nice tips you've got there, it will go along way in maintaining steemit quality.
