@brennen You're welcome, glad I could help. Like I said most of this is just stuff I've heard about through here or other places, but I'm not aware of any hash tags besides #accessibility and #a11y to follow for the space as a whole. On birdsite NVDA used the tag #NVDASR to ensure it wasn't confused with something else, but I'm unsure if that was carried over. A11y is an abbreviation of accessibility like how i18n is an abbreviation of internationalization, a supposed artifact of birdsite's original character limit.
