This is great and all until you (like me) need to be able to differentiate www.example.com from example.com and https:// example.com versus http:// example.com. My website doesn't forward example.com to www.example.com (due to errors on my part that I don't know how to fix, my email is in my profile and if you can help I'd greatly appreciate it).

I don't know if there are any scenarios in which a properly-configured website (mine isn't) needs to differentiate example.com from www.example.com. But I liked the ability to do so easily.
