I own a lightweight blog hosted on GoDaddy. I could not get cron to automatically run, so I manually run it when necessary.
How should I configure cron tasks to make them automatically run on GoDaddy?
I don't have much experience with GoDaddy (I prefer BlueHost), but you could use the PoormansCron module instead of running it manually. Also, if you update to Drupal 7 this is included in core.
I used to use GoDaddy shared hosting and I had cron working with Drupal for a long time. I have since changed hosts so I can't lookup what my exact settings were. However it was something like this:
curl --silent --compressed http://www.example.com/cron.php
