I'd like to use visual cues so that people know they're not on the home page. Here are some tricks I've seen.
The Home Page menu would not show the label "Home." However, is this worth the extra effort when I use an Include file for the menu? I'd have to keep a copy of the entire menu in the Home page HTML file and would have to change it every time I change the menu Include file. (I guess I could put the menu markup in the Home page file as the last step of developing the site.)
The menu label of the page that you're visiting could be highlighted a different color.
There could be a little indicator below the menu showing the path (on which page you're on and how you got there). Paul O'B called it a "breadcrumb" in http://www.sitepoint.com/forums/showthread.php?p=4678115#post4678115.
Any other visual tricks to show the difference? Maybe the text could be arranged differently.
Your ideas or comments?
I tend to make sure that I have a category or article title on the top of the page. For me, that's a clear distinction between a homepage and a subpage.
There's lots of ways you can make a homepage distinctive though I think you are overthinking it. It really depends on what you want to accomplish, the way the site appears, the aesthetic, the need of the audience to distinguish differentiation and other factors as to how, when and why you should go beyond those mentioned.
