Something in SharePoint (2007 & 2010)

There is a funny thing in SharePoint (in all versions)

1) List

With normal list the URL like http://server_name/site_name/Lists/List_Name
With documents list the URL like http://server_name/site_name/List_Name

2) Site

With normal site, all lists have the full controls on the list such as deleting, saving template,...
With blog site, the Posts list does not have permission to delete or save as the template and after save the blog site as template, we cannot restore the site correctly. All views of Posts list are generated as a list with the same name.
