That was my first reaction as well. "We've engineered a competitive advantage so why don't you throw out that hard work the helps our competitors."

I'm not sure where I sit on this, developers who want to be noticed by other engines will continue to focus on SEO, but how many engineers care about SEO that isn't Google?

Honestly, optimizing sites for search is just wrong. It's happening now, because search is not perfect and developers have to work around its imperfectness. But in the ideal future, web masters must design websites for users, not for search engines, in the first and only place. That's what's happening now and it's good sign.

Of course Google competitors must work hard. I don't see why that's a bad thing. It's not like Bing or Yandex are going to disappear in the foreseeable future.
