Yeah, and these days it really isn't a big deal to build things; it's much bigger challenge to actually develop a distribution channels and cut through the noise. I think people are just overwhelmed with everything and attention span is shorter and shorter. And that's the real issue - what I am finding now is that again the thing that really works is good old actual human conversation with potential clients.
Looks interesting, I always have an issue getting confused with all the data and where everything is being a visual person. But, isn't Excalidraw used for that within Obsidian already?
