Join with Contrast Rebellion and build readable web sites, tutorials and blogs. Black is a perfectly fine font color! Gray on Gray is not.
So as a reader of sites not designed for clear easy readability, what can you do besides suffer?
For a while, I was taking to "printing" web articles to PDF and reading them in Evince Doc Viewer with the inverse color settings to get nice white text on a very dark background.
But then I discovered two add-ons for Firefox where you can thwart the bad site design chosen by the creator - No Squint and Color That Site!. The latter is more sophisticated (and has a nice demo video), but I found No Squint to be more reliable. For example on the Gray-on-gray example above that I complained about, Color That Site! had no effect, but No Squint turned it into a reading pleasure - compare and contrast the images below.

In fact, No Squint works great on my blog too. If you want to view this blog entry with a black background and white text, it's a few mouse clicks and then it's just you, the darkness and the picture of ThornyDev, the Australian Thorny Devil, to keep you company.
For Chrome, I didn't find anything as nice as No Squint, but the Change Colors extension can do something similar.
