I spent 6 years building my Kanban as I hated how managers run the boards 3 months ago
Six years of sticking with one product is the hardest part of solo building. Most of us (myself included) struggle with the opposite problem — shipping too many things and not going deep enough on any of them.
The convergence-to-Jira pattern mentioned in another comment is real, but I think the answer isn't "don't add features" — it's "add features for a narrower audience." A Kanban for 3-person dev teams will always beat a Kanban for everyone.
Curious about your distribution strategy. After 6 years, what's actually working for getting users — SEO, word of mouth, communities?
