Advice for Publicizing a Search Engine?
 

So I've spent the past two months building up a porn search engine at http://eveknows.com. At this point, I think it's ready to start getting some traffic and see how it holds up under the load. Any ideas on advertising a search engine, beyond the obvious (links from galleries, forum spamming, etc.)? I've bought some traffic to see if I can snag some bookmarkers out of it, but only 1 out of every 50 or so even bother to search for something, and none of them seem to be coming back. :(

Have you tried submitting to directories?

I'd like to avoid recip links on the main page, so I've held off on most directories.
