Martin Denton is leaving Facebook. He’s irked about their privacy policy–well, not so much about the policy itself but that Facebook’s corner office folks aren’t listening to the concerns of their members.

But there’s another doozy of a reason Martin is leaving Facebook, and everyone needs to pay close attention. He thinks it’s making people marketing lazy–he’s worried that he is hearing about shows via Facebook invites, not press releases, which is certainly concerning for one of the highest trafficked sites about indie theater. (And Martin’s contact info is super easy to find, so that’s going to be a lame excuse.)

And you know what? I agree. And I will add my own criticism to the mix–it’s also making companies very very annoying.

I “fanned” a friend’s theater company on Facebook. I am now sorry I did this. I don’t hear from the company for a while. And all of a sudden I get 4 or 5 invites and mass messages from this company in the span of HOURS. Not weeks, not days, HOURS. And they have nothing to add to their prior correspondence. It’s opt-in spam, basically, and I am opting out of being their fan (or liking them or whatever icon Facebook decides is best).

Which brings me to another Facebook problem. They control the medium. They change the interface around as it suits them. Suddenly, mass messaging is more complicated, and there are complaints about the whole group getting the replies (a huge issue). Once I get the hang of the new interface, they change it again. I don’t have time to learn and relearn.

But beyond these annoyances is a potentially devastating problem. Facebook can decide to shut down tomorrow. And this is insanely important to any company out there marketing on Facebook. If Facebook closed down tomorrow, would you be able to find your 2,000 fans? Would you be able to reengage them? Or would your marketing department be completely wiped out?

Is Facebook still a useful tool? Yes it is. But it’s just that, a tool. And you can’t build a house with a lonely old power drill. And you certainly cannot build a house on borrowed land.

Is Facebook your marketing homebase? If so, why? Or, why not? Let’s discuss in the comments!
