Tim, who worked on IE among other things in his career at Microsoft and now works on Hatteras, showed me tonight that you can set the home page in Internet Explorer by dragging the link from the Address bar to the Home icon on the toolbar.  I had no idea.  I burst out laughing.  It's a neat trick once you know it, but it never occurred to me.  Perhaps it's because I don't change my home page.

Someone's going to tell me that it's obvious, and I'm the only who didn't know about it.  Right.  It's an example of something that's really convenient, if you need that sort of thing, but not very discoverable (unless you often drag things over toolbar buttons just to see what happens).
