I've noticed it's fairly common to have two, or even three top stories talking about the exact same thing or event. At least you get more than one page of comments, from possibly different people on here coming to different conclusions. Sometimes the first comment for a story can shape all those that follow.
Why isn't most server software (that can expect lots of simultaneous users) non-blocking yet? Are there any significant disadvantages with this method?
Can we expect a lot more non-blocking servers within a few years?
