My late father was an assignment editor for a news operation and I can recall multiple instances a decade ago where he told me about some late breaking tech story to which I responded "Oh, yeah, I read about that on
/. a couple weeks ago." I have to agree with the currently-highest-rated-comment that it's hard to imagine Reddit, Digg, or Fark without /. I would even go further and say that your comment moderation system was revolutionary. It's certainly possible to imagine that someone else would have thought about it if you hadn't, but you had it first and the political blogs I read still rank comments by order posted, which is why their comments are a morass of inanity while /. comments (and digg, and Stack Overflow (so long as you have a sufficiently high display threshold)) are often more informative than the article.
