https://readry.com is my latest venture ever since I got into e-readers/kindle. I want to read everything on my kindle and as it turns out, there are no good ways to get anything else apart from "books" on the kindle.
With this I can get my newsletters, top subreddit posts, news, and more, all on kindle. maybe this will help me curb my smartphone addiction.
