How is it a lot different? If I click the misleading "Get app" button, it shunts me down to the email capture which says that even the early subscribers won't get anything for three months.

I don't think the fact that the founder is commenting is relevant. I could chat with people about a theoretical or in-progress product quite easily.

I've flagged this submission. However much work has gone into it, GP is correct in saying that it's an email sign-up. Better for OP to wait until there is a product for people to use.
