Okay...  So why doesn't it say that the search module (for example) 
needs it?  If I go to search's admin/help page, it doesn't say anything 
about the cron job there either.  Here is this fairly essential drupal 
thingy, but I bet ya'll get *tons* of questions about it.

And, thank you.  I wondered why my search wasn't working.  ;)
