MySpace's success came in spite of their technology, not because of it. There's nothing technical at MySpace worthy of emulation. A real technology startup could have done much better.
Google, Amazon, LiveJournal, SixApart, Flickr, YouTube, Craigslist. Most any company who has had highly technical top brass. MySpace was created by suits, that's why it runs on Windows and cost many millions more than it should.
