The most important question that was asked recently and caught my eye was : "why is there a red word duplicate under one of my hubs?" The simplest answer form both Uninvited Writer and Duchess Oblunt were that there was too much content that could be found on other websites, hence duplicate content.

The way hub pages works is that duplicate content isn't a good thing, If one can find it anywhere on the web. People will not look at your hubs if they can find it elsewhere. Still you might ask what is the deal? Other people will not see the duplicate content tag, and it doesn't seem to affect me much. Does it?

It does.

the biggest effect is less traffic and by default less money. The more traffic you can get on an original content hub,The more people are likely to give positive feedback and this can get a career in writing or on hub pages moving. So what is duplicate content then?

Duplicate content is a flag on hub pages that a writer of a hub will get when the hub has much of its content from another source. For example copying a portion of a blog you wrote would be duplicate content as someone would be able to find it elsewhere on the web, it was published sooner on a blog you wrote than on a hub. Make sense?

So how do you write original content? simple, I like to play what if games, if something happened to A what would happen to B? I'll compare something with something else, I'll answer a request (see answer section) I'll look in the Idea bank in my account.

Becausethere are a lot of ways to paste comments to a hub without getting the dreaded red mark on your hub, add more comments, show some insight, make it user friendly, with links and polls, but write different content.

This will help but it's the content we need to think about.  What the right percentage?

In terms of percentages I'll use a low number that everyone can understand 100 words; ( Don't write such a short hub, you'll get flagged for something else-- too short!)

I go with the no more than 30% should be copied content, if that. So in other words: 30 words or LESS out of the 100 words you write can be found somewhere else. Especially not on a blog or website you have.

Also think of this way, if you want people to go to your blog or website, what happens if they see the same content there? Well, they certainly won't go to hub pages or worse, to your blog that you've worked so hard on right?

So best idea: If it's something you want people to read, make it original, and take some time to write it. In the long run it will do two things for you: Increase your traffic and make some money for you.

Writing Hubs is similar to Blogging, teh more original content you have the better your traffic and potential for other things increases.
