I know this is in Python, but it might be of use to you guys: The software
used by the Reddit community news voting site (kind of like Digg) has now
been open-sourced. Here's the article from VentureBeat:
In the arena of crowd voting sites there is Digg and then there is
everyone else. Every once in a while a challenger will come up that looks
promising, but it fades away.
For a while that was Netscape (now called Propeller), then it was Mixx,
but now one of the original (and best) challengers is coming back with a
vengence. Reddit.
Today the service is announcing that it is going open-source. This means
that any developer will have access to the sites' code and will be able to
help improve upon it.
