Representativeness of an assessment of events, results of issue

I was puzzled with the question: why do I, as a user, for example Habra, see news or texts, etc., evaluated by all participants?

This, of course, is also not bad - to know the average vector. But I would also like to see information assessed only by those people who matter to me . For example, my first lap.

It is even better that it was possible to compile a list of “personal experts” in a particular area and regardless of “friendship circles”. And vice versa, I absolutely do not want a person who means nothing to me to influence the assessment results.

Here is the “Personal search from Novoteca” created by I. Ashmanov and K. Any expert in a particular area can make a selection of sites representative of a certain area. That is, I come to such a customized search and look for where the expert advised. Is it really that the issue will be worse than in the general impersonal search engine?

Now all search engines are puzzled by personalized behavioral search. I think this is not correct (in terms of the battle for relevance). I can really get lost in the results of the issue, which will inevitably affect the results of further requests. So it’s not me who should be oriented, but the behavior and the expert’s assessment.

Is it possible on Habré to output from the database the results "common" and "for me"?
