I'm not sure that there is an advantage in having an older account under said system, it is more about freezing the ideologies of the rankings during the time at which you signed up. If you signed up during the time that the discussion was all about startups, then your feed should remain predominantly about startups. If you are a more recent subscriber, you will see more political and "learn how to program" type discussions as presumably those topics are what enticed you to sign up at that point in time. Of course there is danger in that as well, but I see so many lament that they wish it was like it was in the "good old days", where good old days equals the approximate time in which they joined. The way to do that is to let them have the member base just as it was back then, while still letting the site naturally evolve for the rest.
