Nice looking site Useless. I think you probably already know my opinion on your idea of a recipless LL. Don't do it!
LOL, but seriously... the site looks excellent and the color scheme is easy on the eyes. The site may well be/become bookmarkable, but without the recips you still end up with less traffic / links initially. And then you have to question how your submits will be. Will you have a steady supply of submitters that will create regular freesites, then make copies without recips just to submit to you? Is your traffic going to make it worth it for them to do a little extra work?
Don't think i'm trying to be negative, i'm not. But, I was curious about that aspect of the list. Any way you go, best of luck on your new site.
