Great question @positiveim It’s always hard to keep materials up to date! The second edition of my Facebook Marketing All-in-One for Dummies book was just released in December and is still very current http://www.amazon.com/dp/1118466780 Hopefully it will stay current for just a little longer
I also have a Twitter e-book I just updated as well on my website. I don’t want to be completely self promotional here but just trying to suggest some material.
I know Lewis Howes had his LinkedInfluence course but I don’t know if he keeps that updated and LinkedIn has changed a lot recently. I would also recommend Viveka Von Rosen for LinkedIn courses and books: http://linkedintobusiness.com/presentations/
Anyone else have suggestions?
