Just FYI in case anyone's interested, when you put a bunch of emojis after your screen name it makes it unnecessarily challenging for people who use screen readers to read your posts and follow you. The screen reader will read out every single emoji description every time you pop up in their feed.

If you feel like you don't know what you don't know about accessibility, it can help to follow folks who discuss assistive technology, accessibility and disability. Here's a list of people who post a lot about those.

So. We’re doing alt text discourse again. COOL. Welcome to a primer.🧵
If you're unfamiliar with what alt text is, what it means, and how it's used around here, the following may be helpful.
Although it's still a very underused feature, users can add "alt text" to any image

If you're new to captioning videos for your content, you might feel as if you don't know what you don't know. Meryl Evans' "Does Your Video Make These 6 Common Caption Mistakes?" is a great resource to help make your captions better.

When writing alt text for an image of text, it's not enough to just write "screen shot of text from article." Sighted users get to know what is in that screen shot, so why don't blind users deserve the same? The alt text should include all the actual text in the image.
October 11, 2025 at 8:53 AM
First and foremost, alt text must always be informative and descriptive of the content in the image. It can have character and humor, but it still needs to be informative and descriptive. Alt text is not a place to add easter eggs or jokes for sighted users.

Bluesky has made it easier to add alt text, but some still struggle with HOW to write alt text. Sighted users who don't rely on alt text might feel overwhelmed. They might have questions on what details to include, or how to get started. This post from Veronica Lewis is a great resource.

The other reason is that many, many screen readers will just blurt out the Unicode name— and sometimes those names are long, make little sense to people not used to seeing them, or don’t mean what you think they mean.
And especially do not stick hashtags in alt text.

Avoid emoji icons in alt text. Emoji icons are a visual element, so it's counterintuitive to add them to non-visual content. You'll likely confuse people with messages that don't make sense. In alt text, use plain text, free of symbols, icons, or any weird special characters.

Dude. If you're going to skip the alt-text, putting in a screenshot is foolish AF. This isn't Twitter; the link generates its own preview. All you do by inserting a screenshot is making the preview inaccessible and unreadable.

I have low vision and I rely on alt text and image descriptions to provide context about images on platforms like BlueSky. If you don’t know how to write #AltText yet, I have several guides on my website that can show you how— take the #AltTextChallenge! veroniiiica.com/how-to-write... (1/10)

My view on alt-text; just include it. For four reasons:
📖 it makes those who have low vision or other challenges able to interact
📖 you can write an essay of 2000 words
📖 it’s the best writing prompt ever
📖 you can use alt4me or dictate alt text so there’s no excuse

1) USE ALT TEXT
2) Use it sensibly. It's to describe the picture to someone who can't see it. That doesn't mean you can't be funny or cute, but it you just use it to make a joke you're basically telling visually impaired people they matter less than your snark. Which, no.

Reminder that all those cute fonts, emoji laden “checklists”, memes like the summoning circle, and ASCII art are hell on screenreaders (more specifically, on people who use them). Some of them don’t even let you skip posts that sound like you’re summoning Cthulhu.
