Thanks also to Bill Slawski, who over the years has kept on top of this material, and to whom we all owe a great debt.
+1 -- Was thinking the same thing earlier myself.
Hummingbird might be limited to these, but I'm thinking that it necessarily goes beyond them (and I'm guessing that you would agree with that.)
Absolutely -- The last 3 I added appear related to and incorporated within, but not encompassing of, the Humming Bird algorithm. The diagram/image on the "Humming Bird Patent Application" [ here: [pdfpiw.uspto.gov...] ] mesh the 3 together for the selection process, but there are still 200 other variables [including: PageRank, Panda, Penguin, etc.] that finish making up the whole of the Humming Bird algo.
