well the title of the article is 'your words are wasted' - which is a bit hyperbolic if you agree with the diversification view. That title - along with the content that follows - seems to imply that it's a waste of time if it isn't going onto your own blog.

Don't get me wrong - I would love for there to be a decentralised social graph that allowed us to eat our cake and have it too. But that aint going to happen any time soon.
