Google will punish your blog if you post the same article that is already being published anywhere. So You must publish article in different version in different place.
If you post a low quality article that you are happy to syndicate to other sites, why care which site ranks the article highest as long as your back-links are in place? That site has better SEO for the keywords so could send more traffic to your signature links.
If you write a good quality article for one of your main content pages then I think it is foolish to syndicate it out without making some changes. How hard is it to change the title for example?
Agreed with Andy101, you did the reverse posting. However, In my opinion, in any case, you should not post any content on your website which has been once published. Always publish original content for distributing. If you are too lazy, then spin/rewrite your content and republish it to other websites.
You need to promote articles only with the useful and fresh content and then only people will engage to read your article and you can get benefit of your article submission. But if you post article that has been published before by other then there is no any mean of such article that containing old information for people. And it will not be helpful for you to get results. So just provide the unique content in your article so that people and your site both can get the advantage of it.
Never publish your content on anyother sites instead you can have your own blog where you can update the blog with unique content an a regular interval of time, which in turn brings traffic to your site.
So, how do you think Google is determining whether an article is low-quality or not? Certainly, they can look at issues like duplicate content (which would be one indication). But, what about off-page factors? If Google sees a new URL and that new URL gets links and gets posted to social media sites within a short period of time, then that could also be an indication of quality.
