String substitution placeholders
I saw a fun toot by Skye \ Uzi where they found a way to cause a little text substitution by instances with a certain string. This suggests that you will see your instance when I type $INSTANCE$host$ (or not, IDK) which, I think, is a fun little bit of technical hijinks either way.
Update: Skye \ Uzi is too clever by half.
void.rehabSkye \ Uzi :flag_transgender: (@skye)People on $INSTANCE$host$ will get excited about seeing their instance mentioned before realizing the post uses a trick to serve a different post based on the instance used to view it
