Ask HN: Do you zoom in to read webpages?

As a man d'un certain âge, I'm wondering how many of you read webpages at the default zoom setting of your Web browser, and how many of you zoom in on pages to make the text look bigger for easier reading. I think I am older than most participants on Hacker News. I almost always zoom in on webpages, from time to time discovering webpages that aren't designed to be easily resized. (Hacker News is well designed for zooming in.) What is your practice in reading webpages? Do you take every page with its default settings, and use your browser with its default settings, or do you resize pages?

I normally use Google Chrome as my main browser on my dual-monitor Windows 7 office computer, and it stores my preferences site by site. I usually zoom in on any given site until the main page text goes all the way to the edge of my screen, which typically is about a 175 percent zoom. I am designing webpages for a couple organizations right now, so I am testing on a variety of computers, monitors, and browsers, to make sure that what I design doesn't break with viewed with different hardware or software from what I habitually use. I've been reading up a lot about the latest advances in responsive Web design and the new versions of HTML and CSS. I suppose most of you are younger than people who need to adapt in this way, but I have become very conscious of middle-aged people with presbyopia as I browse websites, and I want to make sure the sites I build are friendly for them.
