I LOVE my own sub domain. I know that my articles are mostly very good - and I like that they are NOT being judged next to sub par spin or otherwise poor articles. They stand or fall on their own within my subdomain - which also stands or falls on it's own, and I'm the guy who gets to either do it well, or screw it up.
As wesman says I don't want my work to fall in the eyes of search engines thanks to some crazy person who signs up just to promote thier own blog or website with just one useless hub.
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.
