If you run a blog that has white script on black background, I won't be reading you. It's not that I don't like you, but it's that I cannot, literally physically cannot read what you write for more than fifteen seconds.
There are a couple of blogs like this who's authors I absolutely love to read, but I can't do it. My eyes just won't take it. Maybe it's just me. Maybe I'm getting older (*&%# you Father Time!) and can't focus the way I could in my twenties. But if you have white script on black, more likely than not I'm ending up skipping your writing because I cannot physically read what you put out.
This sucks. And maybe it's evidence that Father Time hates me and is making me a whiney little bitch. But I'm hardly the first in that regard, eh?
