Why can't I post my articles on multiple websites on the internet? I can only post them here?

No, No and no ...I guess you need to read the TOS of a site before you start writing there. The TOS clearly says that you have to write unique content for Hubpages. Most of us write on many sites, but we link across our articles so we can get readership for them..but if you write useful stuff it is bound to float up on Google searches and more people would be reading your content.. Go to the learning center (click on 'help' at the top of your screen) and read about keywords research and back linking and how to get traffic for your hubs..hope this helps..

I wouldn't waste an article on this site when it only gets 50 views in 2 months.

Hub pages calls your original articles as duplicate. What can be more painful for genuine writer.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
