An anonymous reader writes: For Web 2.0 start-ups, it's become common to release products in beta, before they're quite ready for the consumer market. But Andrew Keen, author and entrepreneur, says it's time to abandon the "beta cult", which replaced "the adult ideal of perfection." Keen laments today's start-ups and the entrepreneurs who run them ("even the sloppily untucked clothing of the unshaven entrepreneurs seemed to exist in a puerile, petulant beta," he says). Instead, he champions companies like Microsoft which, in being "immune to the adolescent beta cult," don't release unfinished products. Google, on the other hand, announced the Chrome Browser OS before it exists. This will change in the future: "The simple fact is that unfinished products are unsuccessful," says Keen. "Thus the cult of beta will, like the Web 2.0 euphoria and other fashionable ephemera, eventually pass."
