I have tabs from like 6 months ago. Modern browsers have gotten pretty good at hibernating unused tabs and restore when needed. And this website is extremely light, it gets restored in milliseconds.
The browser history contains a lot of junk and I don't want that saved forever. Curated tab history is a bit different. It's stupid for sure, but also a bit comforting to keep the most important articles and such. For anything I really care about, there's always ArchiveBox.
