I have been blogging for quite a while and recently I signed on Tumblr.com and created my profile on it. After that, I downloaded and installed a Wordpress plugin that automatically share my newly published post on Tumblr. Now, I can see the same post on different URL's. One is my own blog and other is the profile that I created on Tumblr i.e. MyBlog.tumblr.com. The question is will Google treat this as duplicate content, though I have provided the original source URL below the post. Please reply.
