I'm not a scientist or anything, but 180 characters per line is perfectly readable to me (more than that, I'm not sure...). So is just 80. The only time I will really notice a difference is when a paragraph becomes too many lines. Here's some things I find unpleasant while reading: w:c:mathmagician:Lorem Ipsum gives a good comparison of what I like to read and what I don't like to read.
 * 1) Paragraphs more than ~5 lines long
 * 2) Not enough spacing between paragraphs (Wikipedia suffers from this)
 * 3) Too many multi-line paragraphs one after the other. Stories with dialog are great for readability because you'll often see standalone lines when characters are speaking.
