Facebook is a long way from becoming a ghost town, it's just currently more like a superhighway littered with billboards. We'd really like it to be a cosy cafe where we could enjoy a cup of coffee and conversation with a friend or to.
As a referral engine, staying on someone's radar on Facebook is hard work. The secret to my Facebook work is consistency. I'm checking accounts and business pages for several clients on a regular basis. When checking in on Facebook I look for things of value to repost to the people who follow (or friend) me because of my social media info. And cats. Always with the cats on Facebook.
