Great Scott! David's right again.

I met David Meerman Scott many years ago and was impressed with his perspicacity regarding social media.  He was a man ahead of his time in understanding the potential for these new platforms to reach out inform, and entertain--as well as to waste your time!

Even now, he regularly produces gems of insight.  Here's one from just a few days ago. A teaser:

Social networks are a great place to share content, to interact with others, to listen in on what’s happening, and yes, if approached carefully, social networks can be a way to get the word out about you and your business. However as I review people’s business-related social streams I find way too much selling going on.

As a way to think about your social activities, I’d suggest you should be doing 85 percent sharing and engaging, 10 percent publishing original content, and only five percent or less about what you are trying to promote.

If you are trying to sell, it's well worth your while to read the rest.
