Only text that lacks intrinsic content--like results--should be readable from 3 feet away.
Most text should be 10 points.
Small text has an added advantage: most senior researchers, who undoubtedly need reading glasses, will be unable to read your work.
Make lines of text so long that the readers lose their place when trying to find the next line.
Use a non-standard typeface. Center all type--or be bold: use only right-adjusted type.
USE ONLY UPPER CASE LETTERS. On the internet, writing in all capitals is considered to be rude and shouting-- and you do want to assert yourself, dont you?
