I see a lot of complaints about scope creep and vision drift here, so I'll add a different perspective: I use Notion right now, but have been considering a switch to Obsidian for a while now (variety of reasons, chief among them a desire to reduce my own dependence on US-based tech platforms and tools).

The lack of something like Notion databases / tables was the last thing stopping me from migrating over; I found this feature really helpful for organizing my thoughts and tasks as I want them organized, and not having it would have been a noticeable UX regression for me.

With this launch, I'll take a deeper look. It's that simple: it provides a feature many want, largely because it's seen as a killer feature of comparable closed platforms.
