Here's the article at author's website http://taligarsiel.com/Projects/howbrowserswork1.htm.

"Tali published her research on her site, but we knew it deserved a larger audience, so we've cleaned it up and republished it here."

That's much better; thank you!

I was just about to post something to that effect. The site feels like Microsoft MSDN. In the case of documentation or technical information, you'll never go wrong by using a large, easy-to-read font with a strong contrast between background and text color.

could not agree more. very hard to read, seems opaque in a way when trying to read the text.

Update: so, i removed the dot texture on the page and also changed the google webfont to "gudea" instead of "open sans" and it seems to be a lot more readable. i think if the authors of the site changed the font to something more readable, all would be good. the font i choose was just picked at random.

see my edits: http://dl.dropbox.com/u/103326/after_Gudea.png

readable http://readable.tastefulwords.com/ makes a reasonable job of it, but it's clearly not built to be read.

You might want to try readability: http://www.readability.com/

readability is a great option, but this site is brand new. it's not like it has outdated typography, etc.. you would expect the site to be readable without any tools :\

I actually used readability to prettify the article and send it to my kindle. Sadly though, it stayed on my Kindle for a long time, hopefully I will read it soon.

It really is.

javascript:void((function(){jQuery("body").css("font-family","hevetica,arial,sans-serif");})());

Changing it to Helvetica (or Arial) make a little bit easier to read (Putting above code into URL bar does this).

Best way to read it is selecting all the text. The white text on red "background" is not bad.
