Here are a few ideas for information you might want to store in a list:
- a list of items and how much they cost - SharePoint has the ability to automatically calculate the sum
- a list of questions and answers - you could include a "category" field and then group the list by category
- a list of people with their contact information
- a list of award winners
- a list of events - SharePoint allows you to create views of the data that allow you to only display the current events
