<blockquote>If I were running a $1B site, I could do it with IBM, Oracle, or hybris and my SEO team would be handing specs to developers to implement. The deciding factor between those 3 platforms [...] would be things like total cost of ownership, native mobile support, speed, search, content management, merchandising features, and the ability to hire subject mater experts. Frankly, the implementation team would be more important than the platform.

But if I were running a $20M site, I wouldn't want to do it on any of those platforms. Note: Most $20M/year sites, want to be $200M sites, so it's still very common to see IBM and Oracle used on small sites, but they often struggle.</blockquote>
