If you did a search for widgets - you would only get the paid pages from their directory (ok - not all are paid - but you know what I mean)
Then there was a link at the bottom that said webpages that would give you results from google.
Now the teo are mixed in, but you can still get directory
only results by clicking on directory.
So to answer your question - you will automatically be included in the default yahoo results if you are in google. You might not have the same position - as they mix the two.

I always list, especially for new sites to provide a strong backlink and ensure the Googlebot visit. Also a little known fact, once you list with Yahoo you suddenly get listed within Alta Vista because AV crawls Yahoo! new additions..this is good because AV is notoriously slow to index.
