Many of my friends start using Facebook not because they want to, but because they think they should. Then, after a few months, they get why Facebook is such a beautiful thing. Facebook is a way to stay connected to your friends' daily lives, with a minimum of effort. No need to send out an email blast to let everyone know you've got a new job, found love, or the perfect latte. You don't have to set up a photo gallery on your me.com account to share your reunion pix. Instead, you can upload your pics from your digital camera or even from your mobile phone on the fly. An old friend of mine who lives on the west coast wrote on my Wall the other day: "I feel like I know you better now than I did when we worked together". Then there are my marketing friends who think their clients should be using Facebook. But, the "how" and "why" are a mystery. Before that next client meeting, check out Hubspot, where you can find out how your clients can use it to engage with their clients.
