> How many people are looking to use Obsidian purely for personal use?
The overwhelming majority, if the Obsidian message boards are anything to go by.
I wouldn't want to use a product that only now reached v1.0, for a business. It's not Figma, or a Google Docs type app where corporate use cases are very apparent. At best, Obsidian would be good for a knowledgebase, but there are better wiki tools out there for that.
Obsidian does personal knowledge management best, because of its customizability.
