On facebook, everyone copies and reposts something they went to share, and everyone likes.

steemit isn't facebook, and when you repost something here, NO ONE likes.

The reason is simple. You are getting paid to create "new" stories and content that you made. That's what makes steemit special. We have new unique content here, that the rest of the internet doesn't have.

If you want to use a reference, while you are talking about something, then yes.. you can link to it, or embed it.

For instance, in your downvoted article, what you might have done, is pull a few excerpts from it. Talk about why you think it's a good article. Explain why people should go read it. Then give a link to the article without copy/pasting the whole thing here.

This way when Google comes along, they see "hey! Unique content from exoexo.. this person talked about the article and linked to it. I want to index and save everything he/she said, because it's unique".
