It is an interesting site. I am fascinated by these subjects. However you would do so much better if you could have original content. The duplicate content on your site will probably slow your success rate down a lot. Maybe you could rewrite some of the content or hire someone to create some original articles. It will be worth it in the long run.
yes, you r right, but this is for beginning, later i hope that could write some refreshing original content, what is really hard for this content
