Its a difficult decision to send people to the homepage or the registration page. Homepage makes sense to explore like you say, but then someone might not find the registration button or dislike the frontpage posts and close the page. Registration page makes sense because with an account you can actually start voting, posting and following so you get the full experience. Its also what joinmastodon.org or pixelfed.org do.
I can see how that warning is a turnoff, but the registration approval is necessary to prevent spam bots. And its better to make users aware of that than having them think something is broken. In 1.0 there will be estimated approval time shown, and it will also be possible to use a plugin for automatic approval based on keywords.



Success, you are a sandwich now!
