I kinda screwed with everything else to homogenise all the functions - the FB stuff works, but I've definitely broken some of the other importers.
I can work on fixing them in the future if I need them; otherwise others can look at previous commits!
A first pass at importing my tweets. Includes the code I used to do it.
I've made some manual edits (to add code fence blocks, and fix some annoying encoding issues), but this should be a decent start.
