These are great resources that you have shared.
I added one of the Chrome add-ons called Open Dyslexic to see what it does. It is a font that has a weighted bottom with the theory that it anchors the letters to the page. I'm finding that personally it makes skim reading much easier and quicker!
Also I can see other benefits as it highlights in grey the area that you hover over, to keep the attention of your eye on that paragraph or line. It does seem to convert some of the text (of a certain format I guess) to Open Dyslexic but not all of it.
Here is a preview of what the above post looks like using Open Dyslexic:
It highlighted the post in grey and then the paragraph I was hovering over.
I am looking forward to checking out more of the resources.
