The one comment I did not expect to see leveled against old.reddit.com was that it was slower. I generally hit it only because it is an order of magnitude faster than the main site in Safari. The dynamic/lazy loading of what must be megabytes of assets make the experience 100% jank. The wasted space is actually a preference. The 10,000 ft view is nice and lets you achieve your preferred level of zoom for quickly browsing things, as opposed to being forced to view everything at a certain size/speed.
Oh mobile, consider Apollo.
