Unfortunaely, Google doen't always get it right and reward the original article
This had been going on for years, not just post penguin.
Google will rank the article higher depending on the page rank.
- You write an article on your site, wait for Google to index, then you publish on another site. If the destination site has higher page rank, they will outrank you regardless if you are the author.
- Someone steals your content and publishes it, they will show up on top of you because Google sees it as "fresh"
These scenarios don't always happen but I've seen it often enough.
