Interesting. I would say you’re definitely the minority here, and I would still argue that limiting content width does work better for most.
When you say you sometimes enlarge the font, how many words per line do you aim for or end up with, roughly? You’re describing behaviour that aims to render text more readable, so obviously it isn’t simply a case of “I like text content to be as wide as possible”.
I have no doubt I'm in the minority. My preference is basically the more words on a line the better, to reduce as much as possible a) my eyes jumping to the beginning of the next line, and b) having to scroll the page and have my eyes sync to the scrolling. The only reason I enlarge the font is to make it large enough to read comfortably. I don't make it too big, though, because then the lines start to become shorter, and I'm back to the original problem: having to keep jumping to the next line, and scrolling fairly often (which is my biggest complaint because I find that even more distracting than moving my eyes to the next line).
