@alx Sometimes, when I really like a picture that doesn't have alt-text, I write some myself and suggest it to the poster. Explaining that I can't boost it because of my blind followers who have a right to be part of the conversation.
Is it just me or the majority of posts that I am seeing now containing images don't have any #AltText ? One thing that I really liked here when I joined some months ago was exactly how people cared about #accessibility issues. I know cultures suffer loss when communities grow, but we should always encourage good practices to be maintained.
