It is better to test your system than to continue building to then realize that all work might have been in vain.
That is - btw - exactly what happens to most startups who develop tangentially to market need. What determining market need is to startups is what testing the system for usability for every obsidian user.
I noticed a “I am sure it’ll be of use some time in the future” mentality here often and I don’t like that mentality.
I would rather talk to people who judge their workflow and data collection honestly and are willing to throw it overboard if the assumed use does not come up within a set time frame.
In other words I prefer ruthless goal orientation over a collector’s mindset.
