What you’re learning by “renting” your pages on Facebook, Twitter, Pinterest, Tumblr, Blogger, Wordpress.com, LinkedIn, and Google+, is portable, which is to say that everything you’re doing, experiencing, and learning will improve your ability to engage and market online into the future. So, that’s good.
Invest instead in engaging visitors, drawing online attention, encouraging social sharing and telling compelling stories
The downside is that all good things come to an end. The recent Facebook IPO backfire reminds us that even Facebook, with its 900 million active users worldwide, can still fall, as did MySpace and Friendster before it.
