We're also trying to find the "hook" that would make such a site more useful to newsletter readers.
For individual articles, do you find sites like Hacker News or Reddit good for that purpose? I think there are certain authors whose writing is consistently good, and those are the ones we're trying to identify -- curious what you think.
I looked into scraping substack to find individual writers and highly rated ones (through subscriber counts). There's some good writers like Heated by Emily Atkin. Though - do I want to read climate change articles all the time? I found that for some newsletters I lost interest after some time or some topics didn't interest me.
Reddit is also a crowdsourced recommendation system with its subreddits. I find some subreddits good like r/dataisbeautiful. I found this subreddit through a referral from a friend.
People use twitter to ask for good newsletters as well.
I ended up with a fresh email inbox with 100s of newsletters and realized that it becomes a lot of junk. Only some of the daily articles are topically interesting to me and it becomes a game of subscribing and unsubscribing.
I think what I really want is to have individual articles rated and to only have those surface for me.
Another idea I had was to store every newsletter (which is usually just text and images) and then ppl can turn on a faucet to add/delete newsletters to their feed (fb style).
