                I am the first user
            to earn at least 30,000
            reputation points each

                 
                    on all three of
                  Stack Overflow,
                 Server Fault and
                     Super User.


         I was also the first user to
surpass 10,000 and 20,000 points each
          on all three of those sites.

comment How do I interpret the results of the `ls -l` command?
