Love, love jq...after awhile, I realized I was twisting my brain too much to get bash to do what it wasn't meant to do, but I got a lot of mileage of just playing with APIs because of how jq made it so easy. I came up with some fun lessons on how to use jq and other CLI-tools to tour the Spotify API [1] and to mash up images from Instagram [2]

(note: while I say that I like the command-line, I'm not die-hard enough to have stopped to learn awk, so take that fwiw)
