Google has all sorts of stuff built on top of PageRank for their search engine - it's probably safe to say that their implementation is thus 'better' than the released algorithm. One of the RF creators consults with a company (http://www.salford-systems.com/products/randomforests http://www.salford-systems.com/products/randomforests) on, I suppose, better implementations. Some people have claimed it's better than the R implementation, I don't know. RootSIFT being patented is kind of my point - the authors created a (good) algorithm and haven't released it for free use. It's within these kinds of niches that Algorithmia can succeed.
