I did the same for my personal wiki; however, I don't think Obsidian is currently set up to handle the type of group wiki/task management that Notion is often used for.

I love Obsidian, and it's exactly what I was looking for. Notion has a slightly different usage for people, so it's not always an easy switch.

Recently did the same. I wish Obsidian had some of the nicer looking UI elements (such as editing a table without switching to markdown). I plan to stick with Obsidian for now, but am looking for something else since Obsidian is too limited(but the devs are great)
