+1 For Roam. I'm a long-time Org Mode user, but was always waiting for something like Roam to take its place. Roam is a great example of how getting a few key features right can launch a tool into a league of its own.
I started using Roam last month and it's been very effective for me. The linking between documents literally stitches all my work together and let's me flow and wander, improving and adding each time.
