I've used it at previous places of work. It's nice. Snappier and better looking than Jira at least. One of the previous advantages of using it is that everything has a keyboard shortcut, so if you learned that you could be very efficient with it. Nowadays, however, when an LLM is shuffling my tickets around, that feature is kind of useless and I'd probably prefer Jira simply because they integrate with everything under the sun

Not an ad at all. I've been using Linear for the past 4 years. Been using Jira, Trello, GitHub Issues, and other issue trackers before. Linear is simply incredibly better compared to Jira. I had tons of colleagues in my current team and former teams who were skeptical at first, tried it, and 2 weeks later wre saying they would never come back to Jira. I've seen many similar comments here on HN over the past few years.
