I love ifttt!

Was curious about the two separate pdf files that come with the software, the one seems to be a few years old and created for the other/older video software pre-hom. Then there is an hom specific one but they both seem to have the same recipes?

What was the strategy behind the specific sites used out of all the available ones, and the specific recipes/sequences/tiering vs direct etc?

Also in both files, the 6th recipe just redirects to ifttt's homepage https://ifttt.com/recipes/187770-hom-ifttt-6 but I'm sure I can find a replacement recipe to accomplish the same thing...
