I think that would be interesting to create a TOP 10 or TOP 100 of the sites webs of the members of x10hosting. A list by languages: English, Spanish or French
What about Aardvark Topsites (www.aardvarkind.com) All you have to do is run the program on your server anyone who wants to register there site can do so. If they do they will then get a picture to put on there site showing their position on the list.
It works by counting the number of times the picture is called up. Just an idea
