isponage shows about 3 thousand some thing dollars a month they made in ad's.
with there very simple site probably about 100 something a year to maintain.
257,156 Traffic Rank in US ranked in alexa.. i dont really trust alexas ratings to much but thats a good rating coming from them.
i'd say my opinion there making probally about 5,000 to 6,000 a month on the website maybe more. with all the exposure they got some abc and other websites "https://twitter.com/blastapps".
