I saw yahoo result with a variation of self referencing links for one term. The links on page were the first few words of each paragraph and they linked to that paragraph with a good choice of anchor text.
I don't see that making the entire article rank more highly but if it ranks #1 those extra links in serps might help.
Making sure a search user finds what they want is tops for search engines but unfortunately that means the end user finds pages that are MOSTLY not what they wanted. Round and round we go.
