that site is a lot fluff and soapboxing with no real value.

it give examples of sites with bad contrasting, but don't show what they would look like fixed up. Rule #1: if you're going to complain about something, give me a demo of the point you're trying to get across so I can see the benefit. You should even go as far as explaining the process you used.

just directing people to a bunch of links and "read this guide" does nothing
