Reading Between the Lines

So how does a beginning healer learn about their class outside of asking people in-game? Blogs, forums, and websites such as found on my blog reading list. Now, why do I bring this up? Due to some recent down time I’ve done a lot more reading of various blogs and forums.

Now, most of us read blogs through a feed reader, but if you post a picture to describe something, sometimes that doesn’t show up in the feed, so now the reader has to click over to the actual blog. When I get to a blog that has a black background it immediately gets an “x” mark in my mind and I’m a lot less likely to browse through the pages.

Any readers that have stuck with me may realize from previous posts that the usability of my UI is a big factor, and this translates into blogs and websites. What this means, is that I’m familiar with the research on text legibility and readability. You’ll notice on my own blog I try to use a single (accessibility friendly) palette. Additionally, any colored text I use is dark saturated to be almost indistinguishable from black or is a content header with appropriate text size and spacing to make it more legible.

Please will folks stop with the horrible colored (or white) text on black/dark background designs for their blogs! Using light text on a dark background, reduces the readability by 10% or more (Nielson, 2000). That means there is a LOT of empirical research demonstrating that reading white or *shudder* colored text on a dark or black background is more difficult, slower, and will produce eye discomfort for the reader.

For a good (colorful) demonstration of what not to-do see: Systems, Applications, and Products (SAP) Information
