Welcome to my blog, Mark 42
Who knows how many times I’ve tried to build and maintain a blog. Life always gets in the way.

Dear developers,

If you are going to require me to use Discord to learn about your product, install your beta, or “jump the line” on your waitlist, that’s a hard “No!” for me. Instant delete.

Especially if your product revolves around digital autonomy and privacy. 🤪

Sorry (Not sorry)
