Aye, but it's also possible to waste an incredible amount of time on HN. I'd call it my main internet vice after lichess. Both are outwardly better than say, TikTok or Reddit, but if you're spending hours a day flitting unstructured between content, you're subject to both the fragmentation and time sink problems. Same as someone who spends the same amount of time caning TikTok. A little healthier (maybe not lichess) and less intense, but I'd argue also damaging.

It’s my most used website according to Apple Screentime. So you’re probably right (daily average around 30 min).
