"Today, Pinboard is Ceglowski's fulltime job, pulling in $250,000 in revenue over the past two years. He says the site has 25,000 registered users with about 18,000 active ones each month. Ceglowski's only costs are paying for server space, and Pinboard makes money by charging customers a one-time fee of $9.50. (The fee started at $2 and goes up a penny with every 400 people who sign up.) There's also a $25 a year archiving fee for people who want personal copies of links."
