As I see it, you have two choices:
You can bemoan the sorry state of affairs in this modern world, or you can stick your toe in the water first, then slide your entire foot in, get used to the temperature a bit, take a deep breath, and JUMP!
I'm talking about social media in general, and Facebook in particular.
I'll admit that I am no Facebook Einstein. In fact, when my kids saw that I'd signed up and posted a Facebook page about a year ago, they laughed that I only had 10 or so friends in the beginning ("You're not very popular, Dad!").
But the point is, I took the deep breath and jumped.
Has it been a business panacea? Hardly. But I have used it for business, and (to my surprise and pleasure) have reconnected with some old, dear high school friends.
So my advice is, you are not too old. Go ahead, log on and sign up. And be sure to send me a friend request!
