My thoughts on the Google infrastructure update

I was happy to see that Matt Cutts posted an article about Google's infrastructure updates. Most importantly the one talking about Supplemental Results, an area that most SEO’s believe is a sign of a penalty. Like many search engines one giant database with a ton of content in it is just not logical and too expensive. Thus having a second or third database with additional content, makes a lot of sense. You can slice it up any way you want to look at it, but now that they are going to surface these results more often we may have much less to worry about.

The following question still remains in my mind, if you are competing in a highly competitive space. Would it make sense for Google to blend in supplemental results within this type of search? My general thought is no, you would only see the benefit if the results are tail or less competitive. But we won't really know until it happens.
