I would be very, very hesitant to devote any time to sites that offer "free URL submission" or some such thing. Among the world of major crawler-based search engines, you're just wasting your time. Crawlers will find your site more quickly if you have incoming links from other web sites, and they all state "Submitting your URL is not a guarantee your site will be spidered." I think at most SEs, the free submission is a red herring. Yahoo, being brand new, is an unknown at this point.
As far as other sites that offer free submission -- you have to know what you're considering before you do it. Many of these sites will be link farms, and links from those are useless. Links TO those on your own site are grounds for penalties.
Further, many sites that offer free URL submission will also require you to provide an email address and the reason is so that they can sell your email address to spammers (ahem ... direct marketers).
The most important thing about acquiring incoming links is to acquire them from relevant, quality web sites. Find out who are the authority or hub sites in your industry and see if there are opportunities to get a link from those sites. You may have to link to them, as well, and that's actually something that will benefit you in Google -- G likes to see sites that participate in the hub/authority structure of the web.
Best of all is when you produce such scintillating content on your web site that other sites want to link to your site without even asking. So brush up on your writing skills and plan, then deliver, an excellent series of articles and/or newsletter about your web site topic with the kind of information that other sites will want to refer their visitors to. Your time is best spent in this kind of pursuit, as opposed to the hunt for useless links from irrelevant sites that offer "free URL submission."
