People like finding things on the internet and passing them on. By email, message boards, and instant messengers, we have gotten quite used to it.
At social news sites, you get to see what lots of other people find on the internet. That’s a pretty cool idea.
But as the service grows, quality wanes. You can point first to digg, then to reddit. Bad content, manipulation, and a loss of ‘niche’ identity are the culprits.
I think this is the way social news sites are going:
I saw a comment on reddit at some point that, summarized, stated ‘I used digg until it starting sucking, then I switched to reddit. Now reddit has started sucking, so where should I move to now?’. Basically, social news sites might keep reinventing themselves but in essence will stay the same person — like Madonna does. So when the newest ‘hot’ social news site comes around, people flock to it, but it’s really just the same thing with a different name and face.
