I'm guessing that this isn't referring to an IPO and a more accurate title might be "LaunchSky now open to the public"?
I can't seem to change it on my own, will try to get in touch with an mod.
If there is a mod reading this, please adjust the title to: "Starting from HN Post, LaunchSky now open to the public"
I emailed info@ycombinator.com with the request - it seems to be the only access to mod email.
If there is a way I can edit the title on my own, or someone else I can get in touch with to mod it, please let me know.
No one knows what LaunchSky is yet, that's a part of the reason we're posting here.
I'm very disappointed with how they handled this.
