This is exactly why I keep all my notes in Markdown and view via Mkdocs.

Standard Notes is okay. Just know if you want anything besides plain text (markdown/image support) you have to upgrade to a paid plan.

I export my rss.opml and my bookmarks.html files once a week and upload them to Proton Drive as backups. I also convert the html to a md file so it can be rendered by Proton Docs, so I can just click the links from there if I need to.

I am using Coreboot on a HP Chromebook that runs Debian 12 + Xfce. So far, I have not run into any issues.

Full disclaimer: My overall needs for this machine are very light/basic.

I am pretty much done with reddit and Google. My use of those two platforms have dropped to about 5% of my total online time.
