StackExchange is a website I go to when I have programming questions (specifically, the StackOverflow subdomain). You can ask a question, and other people can answer them and vote on each others’ answers so the best answers float to the top. They also have subdomains for home improvement, math, and photography, etc. And now they’ve made another subdomain called “skeptics” for skeptical questions about everyday claims. Here it is: http://skeptics.stackexchange.com/?tab=hot
