Give me one reason for Google to use Panda and Penguin (which takes ages and ages to roll them out) on a fast and precise core like Hummingbird?
Someone correct me if I'm wrong, but my impression is that Panda and Penguin assign scores to pages and/or domains. Hummingbird looks at those scores (along with other index data) when it retrieves, organizes, and serves up search results.
In other words, the Hummingbird algorithm works in real time, but the underlying index--including Panda and Penguin data--is updated more slowly (e.g., as or after pages have been crawled).
