Twitter is like a river in which we drink. The river flows continuously. When we are thirsty, we dip our canteen in and catch the water at that exact moment and begin drinking. It’s impossible to catch the entire river. Sometimes our canteen catches things we don’t want in our water. We then create filters to extract cleaner water when we refill our canteens. The cleaner the water is the higher the consumable value. The river is the global twitter feed, the canteen is your following feed, filters are the lists and search tools and the water is valued content.
