Thank you @kissofearth for your comment.

Point number 1,3,4,7 is what can be fixed if people stop for a while in making personal profit and actually think about the community as a whole.

Unfortunately, this rarely happens.

if after writing something original your posts goes unnoticed, your start to lose the interest and over time this thing alone start to discourage you

I like to curate. I actually curate and comment more than I write posts. However, the lack of good curation tools makes so difficult to do that.
