People are generally lazy. They like it when things are efficient and provide more profits than the costs. This is no different on the internet. If there are 10 cute pictures of cats, why not put them all together in one convenient list and spare everyone the trouble while counting down to give the satisfaction of seeing the cutest cat? People would choose not to spend 2 minutes watching a video on Buzzfeed if the same thing can be portrayed in list form. Lists have grown recently in interest and desirability due to this mentality. Some websites on the rise due to lists are Buzzfeed, Thought Catalog, and even this list of lists.
