Very nice. Would be even better if I could just click on the topics to select the ones I wanted to view in the newsletter, instead of having to type them by hand separated by commas.

Good idea. I’ll add that to my todo list.

Really cool! How do you determine the topics for an article?

I also see some topics on the full list that probably shouldn't be there - a gmail address and a random string of numbers.

Thanks! An article is categorized based on the keyword search result powered by Algolia, which is quite simple as of now.

Yeah I’m aware of those bad user inputs, I’ll probably add some basic validation for that when I get a chance.
