From the Sarcastic Gamer editorial: "Sony announced today that the Playstation Home Open Beta has been pushed back until Fall '08 and the Closed Beta will be "expanded" both in length and number of testers. This announcement seems to have rubbed a lot of people the wrong way as if there is somehow this technological Utopia they're being told they can't enter yet. Sony (ie. "the man") is somehow keeping them down. It seems like some of you think this is somehow cruel and unusual punishment. You know what? Suck it up guys.
It's generally a good idea to delay if someone's coming out with software or a service and THEY say it's not ready. Shigeru Miyamoto has a pretty good outlook on this kind of situation with reference to games (and no, Home isn't a game, but his outlook applies here nonetheless). He said "A late game is only late until it comes out, a bad game is bad forever." Obviously that statement was made before the "release now, patch later" mentality of today's console landscape was commonplace or even possible."
