The folks at ChangeThis regularly offer "manifestos" on a wide range of topics. There's always something worth reading in each batch (although I really wish they'd stop distributing them as PDFs). The standout this time is Debbie Weil's Beginner's Guide to Business Blogging.
Most ChangeThis documents are free, but they occasionally charge--the "Beginner's Guide..." is free for one more day but will be $29 thereafter.
Even if you don't feel like paying for the "Beginner's Guide...", I definitely recommend subscribing to their bi-weekly bulletin.
