Most Annoying Website Mistake You Can Make

Since I have encountered this problem a lot lately, I declare it to be the #1 Most Annoying Website Mistake.

Using light gray text on a white background.

Why on earth would anybody do that? Don't you want users to read your text? What do you hope to accomplish by making the text so faint it's nearly illegible?

Here's an example of what I see on websites and blogs quite often:

I am making my web text nearly invisible, so you have to squint and strain to see it and I don't care what you think about it because it's my right to design things any way I want to!!!!! Ha ha ha ha ha.

Do you get my point now?
