Precisely the same thing is on my mind as well. Would greatly appreciate if you could let me in on any useful answers you get.
Meanwhile I'm planning to try it out for myself, and actually go ahead and post it to other sites I subscribe to. Let's see what happens!
If the articles are your own but appear elsewhere on the web it will take a hub score hit as a result, but as near as I can tell it's not against the site's TOS as long as it really is yours. It seems that if they're posted here first and then on other sites they do better, though that could be more coincidence than fact based on my experience.
I asked some time ago about how unique does something have to be to not trigger HubPages flagging us. Naturally, someone answered something like "unique is unique". (What was that Bill Clinton bit about what is is?...) Anyway, that's not a good answer.It's not "black and white" for what HubPages and various other sites are looking for.
In reality it has to be only pretty much unique. The problem is determining where the line is drawn.
I doesn't look like paragraph substitution alone is good enough, any more. Look into "spinning". Rewrite every sentence of the whole article with major words or phrases alternatives.
Here is a partial sentence in "spin notation.
Diabetes is a {serious|dangerous} {disease|illness} that {affects|strikes} ....." A spinning program will assemble articles for you by randomly selecting one word (or phrase) from within each set of brackets.
You could give that a try by posting a spun version of your Hub elsewhere and see that HubPages does. If HubPages then flags you, you could then substitute other spun versions to one or the other places.
Maybe try a couple of times, but if still a problem, I, myself would delete the Hub if I was going to publish several other places.
I did once try spinning in the most careful way, my conclusion it is too time consuming to do a really good job, it is just as easy to rewrite from your existing article when the subject is still fresh in your mind, that is especially true if you know your topic well.
Another factor for me is that I tend to write lengthy articles, 1300 words the current one and I can see from previous results that I will be lucky to get 50 visitors over two or three months -- diabetes is not popular -- that is why multiple submissions to other directories would multiply the potential number of viewers, presumably willing to check out information that the title suggests is available in the article.
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.
