I have no idea to be honest. My plan was to post it here, announce it to my newsletter, and then list it on Product Hunt, and then work on remaining features like recursive comments, and address any feedback I get from users. Do you have any advice on how to grow a webapp?

I will be posting my own posts on it just because I write a weekday newsletter, and so I am constantly searching for more information. I think there's a chance some people may look at my site, because there are many other people who have AI newsletters who need to source their information from somewhere. I suspect many are like me and keep an eye on HackerNews for interesting posts, as well as various subreddits, and Twitter, and other misc. sites.
