Brent Simmons, the developer of NNW; the great RSS/Newsreader application has released so far a 2 part series on some handy tips that may want to get acquanted with, to know how to use NetNewsWire a little better. Part one is here, and the second is here.
Some examples are being able to flag news items with the f key, and f again to unflag it; or if you use the built-in web browser you can send a web page through email by going to File –> Mail Contents of this Page or File –> Mail Link to This Page.
So go check those out, again Pt. 1 and Pt. 2.
