Your readers will take the time to tell you that your blog is unreadable or leave altogether.

(Hint: Check the average length of visits on your because it’s highly unlikely new, and potentially loyal, readers will take the time to say, "Hey Joe (or Jane), I can’t read your website because XYZ hurts my eyes.")

You may want to rethink that light text on dark background color scheme, tiny font size, and your complete hatred of margins in the content.

(Quick Tip: A dark grey background with light grey text doesn’t hurt readability as much as white text on a black background.)

And now a tip for blog readers using Firefox; there is a wonderful add-on called Read Easily which allows you to completely disable the CSS styles for a particular website. I’ve used it more times than e-mails I’ve written saying "Hey Joe (or Jane), I can’t read your website because XYZ hurts my eyes."

The onus, however, still falls on the blog owner to fix the blog since this add-on does no good for those who may be using a different browser or loading up the blog in their feed reader.
