I agree on the sub-domain thing. Once on a niche page it's confusing how one should jump to another niche.
And I'll also third or fourth the notion that no one is going to want to add your recip
after the submit the site. Especially a new linklist. Maybe they would for a huge traffic linklist, but why give them a reason not to add you to their recip tables.
Personally, I like your clean design and layout and the css looks clean and well documented. You could probably make more money in mainstream work.
