Sharepoint - Is there a way to get column headers to wordwrap in SharePoint lists?

You can use SharePoint Designer to edit the AllItems.aspx view on this list. Insert this style inside the content place holder:

<style type= "text/css"> 
  .ms-vh2 {white-space: normal} 
</style>

This will override the style for the column headers which is set to white-space: nowrap
