Kinopio is not a knowledge management or productivity silver bullet, but more important: it doesn't try to be. Kinopio's great in the "sense-making" part of my toolkit.
Gather thoughts in one space, relate them to each other, add a silly image when you get some sudden insight that you didn't have before. There's an API if you want to do some integrations or post-processing.
The informal-but-focused interface and collaboration features can be practical, too. Make an Eisenhower Matrix. Make a sprint retro board. Better in my mind than any sprint retro or project post-mortem apps I've seen — but that has as much to do with my own preferred workflow.
It's not tightly integrated with enterprise tools. If you really want that, you'll have to roll it yourself with the API. But ask yourself if that's what you really need. Kinopio is fantastic at what it already does: present a workspace to synthesize your thoughts and encode greater understanding by establishing how they relate. It's not a ticket tracker or enterprise all-in-one, and it doesn't need to be.
