One thing new I’ve learned from on-line Open Mics is visual rhyme, also called eye rhyme. During a recent on-line open mic, the poet shared the word processor screen as he read the poem. The first three lines all ended in ‘e’, though none rhymed is the usual (sound) sense. The critique group I’m in does work off of printed poems as well as hearing them read. No in-person open mic I’ve attended does this, so the notion escaped me.
