    Why sad? Knowledge has increased so much that it's impossible to know everything. Even just computer science it's impossible to know everything. Relevant xkcd: https://xkcd.com/1053/ https://xkcd.com/1053/

Could you give an idea of how many users do you need to get to $1000 a month from ads please?
- dave333 5y ago
  Ad rates are around $3 CPM meaning for 1000 page views you get $3 so do the math. Sudoku sites are unusual since one page view can last hour(s) as the user solves the puzzle.
