What's great
I only started using Linear recently, and I wished I had switched to it earlier. It's the only project management tools that just works and not boring. It has clean user interface, wide range of integrations, and very easy to use.
vs Alternatives
I've used JIRA for many years, it gets the job done, but the UI is always very slow and confusing.
What's great
I've been using Notion for many years. It's a great note taking and knowledge management tool and great for team collaboration.
What needs improvement
I love Notion, but given it's a webapp, not a native app, it's eating up too much RAM on my Macbook. I also find it's become a bit feature creep late, and I'm a bit worried that it's going to follow the same path as EverNote.
vs Alternatives
Before Notion, I've used EverNote, Obsidian and Apple Notes, and many other tools. All of them have different type of problems that annoys / distracts me, but all I want is a note taking tool that "just works"!
