Twitter is like a river … you can step into it at any point and feel the water, bathe in it, frolic if you like … and then get out. And go back in at any time, at any point. But, you don’t have to try to consume the entire river — it’s impossible and frankly a waste of time in my eyes.
My favorite quote and approach to Twitter, Google Reader, Tumblr, and Facebook, and why I love an app like Flipboard so much.
