If your are new to NetNewsWire, allow me to point out the Sites Drawer.
The Sites Drawer is a long list of sites that Brent put in there by hand. Some are sites he reads and likes but many were submitted by others, Brent checked them out and decided they were good enough for the drawer. You’ll find lots of your favorites like Daring Fireball, Rogue Amoeba, Ars Technica, CNET plus TONS more.
Just click on “View” and about 3/4s of the way down select “Show Sites Drawer”.
When you select a feed there is an info-box at the bottom which gives you a short description of the feed and the option to open the site in your browser or to subscribe.
