This is a most excellent place for technology news and articles.
I used to love that brilliant site. It was lile a place for people to discuss mathematics, physics, and other topics, with daily problems, jokes, curiosities, and a lot of things, made by the users, in a format like a social network. The site then changed so fast to become a paid and limited platform with no resemblance to its original form :(
