Exactly what excited and then disappointed me. It's a great idea, but I think making it a service will make some people uncomfortable with natural use cases (ex: diary?) for a tool like this. I have been working on something (probably simpler than, but similar) like this that would be self-hosted, mostly because there's a lot of stuff I didn't want to store on Trello or other "cloud" knowledgebase tools. The markdown editing view from the product page is almost exactly what I was aiming for, so I really like it :)

Honestly I'm not even comfortable with my work interactions being stored on Slack. I would never use a service like this for personal info.

I think a web site is totally okay for this kind of application. Nowadays, I have always a browser open.

But a self-hosted version, for people whom privacy is important, would be great. Are there any self-hosted alternatives? Especially with a nice markdown editor...

I wrote a self-hosted tool that fills this need for me. Been using it since 2008. Content is written in markdown, though it doesn't have a fancy editor. Supports tagging and searching too. Since you mentioned self-hosted, I thought you might be interested.

Personal means it's not enterprise.

Lightweight means not a lot of features.

Why the hell are people so nitpicky
