The feed directory — known as the “Sites Drawer” — really was an old-fashioned NSDrawer.
It was an utterly appropriate use for drawers. (Most uses weren’t.)
I used the term “site” rather than “feed.” Remember that RSS was brand-new to people, and so I wanted to emphasize that these things are websites, that you’re really reading a site.
I also thought that “feed” would scare people off. (It was before Twitter and Facebook and Instagram. The word “feed” was not in common use for internet things yet.)
It may have been the right call at the time — but these days, in NetNewsWire 5, it’s just called the Feeds Directory. (And it’s not in a drawer! ’Cuz they’re gone.)
