Society loves hierachy - when you turn up on site for a call the people who have called and those just hanging around defer to you for one reason. You are above them in the situation they find themselves in. Same with blogging, though the structure is based on numbers rather than knowledge. You get more hits than X so you are better than them, it works the same with booklists (tee hee). If you score more hits then you are better than X. It's natural selection, though wether your offspring will be good bloggers mat be down to nurture etc etc
