So far, I say no. It's a wait and see prospect. Definitely purchase a link in the Yahoo! Directory and submit your site to Lycos/
MSN/Open Directory for the spider to find your web site. Google will find you sooner or later too but always make sure your web site is optimized for the key words or phrases. Use Wordtracker and Overture's tools to research the best phrase possible. All in all, wait and see how your web site performs and moniter the stats.
