Actually, open-source software can be great for accessibility and I’ve been testing Lemmy with a screen reader.

Overall Lemmy is pretty close right now once a few roadblocks are removed. The audio captcha was broken, I helped fix that in the code just a couple of days ago but it hasn’t been released yet (at least not in lemmy.world).

After that I mostly see more subtle issues, not complete deal breakers. I haven’t started looking at moderator features, though.
