As the author of Hummingbird I'm happy to see it get exposure, but it doesn't serve the same purpose as most of the other packages on the list. It doesn't tell you where you should optimize your site to get the best conversions.

The purpose of Hummingbird is mostly just emotional--it feels really cool to watch your site go from 2 pageviews / second to 400 pageviews / second.

At Gilt Groupe, this happened daily and on an order of magnitude larger scale.

Hey Mnutt - that's really cool of you to reply. It's a really impressive piece of technology.
