i see people who have a few original articles and like 50 articles that are just those few rewritten over and over. Does this work well and if so, is this technique more powerful than 50 original articles?
As I previously said, if you think about it, then all articles are basically "rewritten". We all see the same information everywhere, but in different words, don't we? If you can write 1 article, and then rewrite it 5 times, then it's only a PLUS.
bl4ckman is right. Everything is essentially rewritten. When it comes to SE's, they can't tell the difference. I typically take each article I write, and rewrite it 6 more times for 6 additional article directories.
I think its just the same as having 50 original articles. When it comes to selling your articles, it must pass copyscape and dont sell it twice.
