One significant way Mastodon and the Fediverse have transformed digital culture is through the use of alt text. When I look back at my older images online and in my blogs, I rarely included alt text - even though I actively work on accessibility. For some reason, I simply overlooked it.
Now, every time I post something online, I take a moment to write alt text. Mastodon has changed my mindset, and I believe its impact extends far beyond this. The Fediverse encourages a level of consideration for others that no other social networking platform has before.
