From the article: "'They are way ahead of other companies' in terms of supporting developers, says one application builder... 'This a new wave of business,' says [another developer's marketing director]. 'eBay is a supplier, a marketing channel and a competitor. It's a weird arrangement.' ... 'If you can't split it, you can't scale it,' says Eric Billingsley, head of eBay Research Labs. 'We've made ourselves masters of virtualization.' ... eBay is able to publish a new version of its site every two weeks, adding 100,000 lines of code, all while in use."
