Ok - here is my take on this (from a professional writer's standpoint)...

I have been approached on many occasions by marketers who want to know if I will "spin" articles for them. In other words - will I take one (usually mediocre) article and rewrite it six ways to Sunday.

My answer?

No.

Regurgitated crap is still crap. Sorry for being blunt - but that is what it is.

HOWEVER - if YOU write a great original piece and post it on your blog or site - EVEN IF it is derived from IDEAS you got from PLR or ghostwriters - you are still adding value by 1.) infusing it with your perspective/experience and 2.) by later sharing a revamped (and usually better) version of it.

What good is it doing the world if it sits in your archives and never sees the light of day? Maybe you or your site have grown a lot since you originally wrote something - and very few people saw it the first time around.

Ezinearticles.com seems to be welcoming this content "as is" - today, anyway.

My two cents??? Why not freshen it up and revamp it a bit? Do a new keyword search on it (especially if its 6 months or older) and vary your angle slightly?

Same body of research. Similar (but usually better) content.

A win for the directories. A win for you.

But most importantly... a win for your readers.
