I've got an amazing image acquisition pipeline that finds thousands of images a day with little human intervention, but there's barely any user-visible categorization, the navigation sux, the full text search sux, and there's a lot of infrastructral stuff that sux too, but at least you can't see it.

Not only that, but to make the site successful I need to promote it to the sky.

I expect to chip away at some of those issues over the next year or so.
