Ah yes, the cycle of website life. * Hot new community forms at Site X. * Site X residents refer to themselves as the New Wave of whatever. Much better than older Site W because of features/members/dynamic/demographics 1, 2 and 3! * Site X's reputation spreads to former hot new sites T, U, V and W. Site X begins to attract more and more new users. * Site X denizens begin linking articles at T, U, V, W and vice versa.…
Just joking! I totally agree with you. Both in regards to /. but also with websites in general. In fact, the Internet in general. It started out (for me) idealistic and cool and slowly has got dumber and more mass market as normal people started using it. Ah well. We lost something, we gained something. The cool is gone, but there's a lot more of the typical stuff and the Internet is making some of the real world changes I hoped it would only because it is now so ubiquitous (like the change in the Middle East)
I think all discussion sites struggle to identify quality discussion. The whole Karma idea that /. created was very very cool and has worked reasonably well over the years. Certainly, their discourse is wildly better than digg's, for example, and I would submit that Karma is a large part of that. But the problem with Karma is that it promotes group-think and that's where /. is today. Alhough: you could say just the same about HN. Anyone who doesn't love LISP, Python & PG is automatically on the outer. Hating Java is cool, too.
Perhaps group-think is an inevitable requirement for communities to form? Perhaps without some level of shared unquestioned axioms, groups will not form in the first place - just in the way a Christian and an Atheist can struggle to have a conversation about right and wrong because their starting assumptions are just so far apart? I don't know - I'm not sure if there is an answer to this kind of thing, I think that maybe it is just human nature at work.
