*Basically if you want to support this, just sign up to Area51 Stack Exchange, confirm your email address to get 50 reputation (this can be done in your user profile) and then upvote example questions that you like (preferrably those with below 10 upvotes, because we need to get a certain number of question with 10 or more upvotes).* (thanks @niklasb)
