Hi, I'm Ian Greig and I'm a writer in the UK.
I discovered Tana largely through reading Ev Chapman's posts on Medium. She talks a lot about processing ideas that then morph into writing, and that piqued my interest — and she is a Tana user and coach with some good material. That has got me on a learning process withTana although for my main repository I rely on Obsidian with the help of Dataview.
As many people know, Obsidian is powerful, reliable, flexible and a good writing environment but the weakness is that it isn't great for capture. It seems to me that Tana is a good fit with that need and worth the effort of another learning curve
