Content Providers for Bloggers

I have been wondering about a particular website for quite some time now. I figure what better way to learn more about whether it is worth my time than to ask my readers. The name of it is Syndicate Kahuna. It is apparently a free site for blogger to get some filler post. I know many of you write post for pay and need fillers, so I am wondering if this is a good site for this. It would also be nice to get some fresh content to add to your blogs when your going to be gone on vacation. I read about this site on a forum, but no one really praised it or bashed it either. It was more like an announcement of it being available. I would love to hear some input from anyone who has given it a try.
