Aren't those in fact the same?... It's just that you can adjust faster and more granular, but as you yourself mentioned it happened before as well.

And really everybody talks about "the evil fine tuned algorithm" but when I am looking for something to buy many times those "smart" algorithms make very stupid suggestions and I feel the same as in the supermarket - I need to be very very specific about what I want and look for myself otherwise I don't get it.
