Type Matters: Bigger isn't always better

We all know how important it is to get your message across, but there are means and ways to achieve that in the best way possible.
It can be tempting to opt for the 'big' approach and assume that by using block capitals that your message will be more noticeable.
If you have a piece of well written text, why shout it, so it results in an illegible cacophony? A barrage of block capitals is difficult to read and jars on the eye. Dense panels of body text benefit from being set in upper and lower case and your readers will feel more comfortable.
