Cheapest software for web 2.0 PBN management?

Hello-

Thanks for looking at my thread.

I'm looking for the least expensive way to automate and manage a web 2.0 PBN.
A software that will dripfeed spun articles to wordpress, tumblr, etc.

Thoughts?

I don't know of a solution that will integrate all the juicy web2.0's.
However, you might use software or service like fcsnetworker. And for the juicy ones schedule posts. For example tumblr, blogspot allows you to schedule posts. For others you can try ifttt or submitting posts through email where is allowed.
