Ask HN: Are we too homogenous? Maybe, Not yet, But...

There's been a lot of discussion here lately about the quality of front page stories, comments, and the community at large. Is it still focussed, or are we going down the bland road to mediocrity other social sites have done? In one of these discussions (on potential pg bias http://news.ycombinator.com/item?id=165855 ) I came up with a visual of a social website (network/ bookmarking / whatever) being like a pond with a series of ripples. I've now expanded on this on my blog - more reflection made me wonder if the growth of social sites might necessarily lead to homogenization http://www.shirlawsonline.com/blogs/197-my-pond-theory-or-why-social-networks-must-fail and what might be done to prevent it http://www.shirlawsonline.com/blogs/199-my-pond-theory-or-how-social-networks-avoid-failing Is HN too far gone? What can we do to stop it from becoming the next Digg?
