I had a blogpost about five years ago that got frontpaged on HN. It had about 300 upvotes. Google Analytics reported it got 10,000 uniques, impressions about twice that (some people browsed the about page and other posts of mine). Then there’s people blocking Google Analytics so the actual metric would be much higher. I was lucky I used a CDN both for HTML and images, otherwise it would be hugged to death.
