I don’t know how much content there is to share, so you might be overflowing with things to talk about every week. But I fear that doing so much effort weekly could be unsustainable. I would suggest, or hope you consider, a less freqent blog/podcast, like every other week. I think this would be more modest, and easier to maintain. You wouldn’t need to change to title of the blog, either.
Anyway, this is an exciting project and I’m thankful for your work.
The problem isnt gmail, the problem is using an email for this purpose. Switching to protonmail wont make a difference. If you want privacy, use a different communications protocol. For example, use signal, and if anyone wants baby updates, they better install it too, cause thats the only way you’ll send them.
