Dapper.net usefull? Yelp yp.com or yellowpages

Has anybody found dapper.net to be any good in creation of rss for yelp or yp? Can the pages from yp.com be created into rss feeds? I could not get anything when working with yp.com directly but when I went over to yahoo a I got some results but not ideal results.

After a few months at it I am very comfortable in the creation of images and video into full nodes.Yet Text still eludes me...I just can't get full nodes I only get teasers.
