premise: The era of mass media is giving way to one of personal and participatory media. Technology has freed people from having to passively consume mass media content. They are beginning to value their own opinions and offer them online alongside those of the supposed experts. They post online ratings for their favourite restaurant, and they contribute entries to collaborative sites offering advice and answers to questions posed on every imagi- nable subject. They are quickly realizing that all too often the views of a rank amateur are as or even more interesting than those of the experts. It is only the beginning of a revolution that will encircle the globe and affect most people as access to the internet becomes even more widespread.
hypothesis: The penultimate sentence of the passage illustrates the sort of things that people post online.
