I'm not an expert, but based on anecdotal evidence as well as what I was told by a specialist as a kid, Dyslexia technically is just the symptom of having difficulties with reading and/or writing. People will often have multiple "dys" conditions (not sure of the names in English, but difficulties speaking, with math/numbers, with orientation, with one's understanding of their position in space, etc.).

I forget why, but we often bunch all that together and put it under the dyslexia for ease of use when it concerns language/learning. And it's a clearly identified condition at that stage; that can be transmitted genetically (mostly by the father IIRC).

On one extreme, I've met people who could barely read at all, and were totally unable to write with a pen because of dyslexia; but I also know people who technically have common issues linked to it (slow reading, confusing similar letters, etc.) but would not qualify for a proper diagnosis because it is too mild to affect their life in an adverse way. So yeah, it's one of these things that falls on a spectrum.

As for OpenDyslexic, I find it too "wonky" and lopsided. It almost feels like the letters aren't sticking to their line. To be fair, that's how I write, but it doesn't mean I want to read wobbly text.

Atkinson Hyperlegible, on the other hand, helps a lot with things like l,p,q,i,j,I all having clear distinctions that help make words easier to understand.

LMAO. I read the whole first few paragraphs thinking "this doesn't feel different" only to realize it's not in the font.

Neat demo, but:

if we can increase our understanding and give the correct help to these people just think how many more Richard Bransons, Elon Musks or Boyan Slats we can produce

No thanks

Hmm, clicking that link triggered my anti-virus software. Do you have any other source?

That ~~wasnt~~ bad ~~at~~ all

You know, sometimes people say stuff just to be funny and lighten the mood.

I'm sorry, I missed that last bit. What'd you say again?
