What's up with that?  Is there something about it that I don't understand?

Someone please explain.

so you can return to the main page if you are in some other part of the site, its easier than pressing back 10 times

I'm talking about the main page.

another way to refresh?

I guess...

*facepalm* No, he said why do they have a link to the home page ON the home page..... Edit: beaten to it....

OT: It's because they use a server-side command that includes the html code of an external page into the code of every page on the site and that page almost always includes a link to the main page. (an overview of the PHP version of this command can be found here) The reason for using this method is so if you want to change the header/nav bar of your site, you don;t have modify the code of hundreds (or thousands) of pages to make the change. You can simply modify one page and be done with it. The odd side effect of this, though, is the weird link to the main page ON the main page....

^ i thought he meant the home page link almost every site has
