|People often ask me, why I am only active on 2 social networks - Google+ and Twitter.
The answer is that with only so much time available every day to connect with people on social networking sites, I had a decision to make. I could either have 2 highly valuable social networking assets or join another 6 or 8 and have a diluted presence.
I think of it like this:
If you have just enough coffee to make 2 really good cups, then spread it out across 10 cups, you end up with 10 bad tasting, weak cups of coffee.
If you have enough time to be relevant on 2 social networks, yet you spread that time over 10 different social networks, you end up with 10, weaker, social networking profiles. You end up automating. You end up cross posting the same stuff everywhere. You end up vaguely relevant on 10 networks, rather than directly relevant on 1 or 2 networks.
