One thing I learned working with Jeff is that often the need of complex todo lists and kanban boards is lack of focus and direction.
If nobody knows what to work on, sometimes people step in with the kanban board and think that it alone will fix the lack of focus.
That said, I am incredibly pragmatic, I want systems that work with our current community.
I have been toying with the idea of writing a plugin that allows me to highlight any bit of a post on discourse and immediately associate that chunk with a new or existing bug. Mainly as a tool to tie all the separate conversation about one issue together in a couple of clicks.
