@gregmoore Another approach I've wondered about is making it easier to go back and edit an alt tag when forgetting to set it.
@manton I thought about that too since I've had several sessions of clicking back through all my posts to add it after the fact. The most obvious place I think of is adding a button or field to the Uploads page.
@maique Using voiceover to navigate the web helped to convince me alt text is crucial, and that it’s rather thoughtless not to use it. This is how some “view” websites, and eventually it will be most of those reading this, if they live long enough.
