> having a bad landing page suggests you really don’t care about the details, and that’s a bad sign.

That depends upon your definition of a good landing page. Personally, I will pay more attention to a Linux distribution if the landing page has information that is valuable to the community. If it looks like they are trying to sell something, I will just move on. In a way, I treat caring about the details as a bad sign (though I realize that I am just prioritizing a different set of details).
