Why would an experienced programmer be proud of a hit counter? After all, the only thing this program does is tell you that you are visitor number [an error occurred while processing this directive] (reload the page to see this increment). The reason is that there is no datafile; this program is a variant of a Quine. Each time it executes, it prints out the number of previous executions, then overwrites its own sourcecode with a new (slightly modified) version of itself.
