Join me? I hereby declare: 1. I will do my very best to provide meaningful text equivalents for the images I tweet, even when I'm in a rush. 2. I will never be perfect, but I can always get better. 3. I will seek feedback and learn from other people's alt text. #AltPledge

I do wish Twitter made the alt text more discoverable to sighted users. The current state of things makes it harder to learn from others.
