IndieHackers (https://www.indiehackers.com/forum/what-are-you-working-on-this-month-august-2018-5e474c529e) and /r/startups (https://www.reddit.com/r/startups/comments/93o0gf/share_your_startup_august_2018/) does that every month and the community enjoy sharing their project. It also helps get the word out and receive some feedback.I haven't seen something similar on HN so I think it'd be nice to have it here too, hence this post.
Include the name of your project with a link, an elevator pitch and your biggest goal for September.
