Hi ya'll -
I received an invitation to add my blog to a blog network called Demand Studios: demandstudios dot com. Is this is good idea for SEO or bad? Can it help or hurt my SEO? Does anyone know anything about this blog network? And are blog networks good in general or not helpful? I'm concerned about if this would cause duplication of content out there and penalize me. Or can it help and should I try to find more of these out there?
