Nostalgia ain't what it used to be. As slashdot slowly loses its relevance and digg heads for a more general audience to head off competition from Twitter, loyal readers of uber-technical news aggregator Hacker News wonder if it's heading the same way. Seems like the long-standing users aren't posting links to deep, interesting articles anymore, and are instead being drowned out by swarms of new users with more of a social media agenda.
