Seriously the best RSS reader, even though shutting down takes forever, and it's a bit of a memory hog, which hopefully a future upgrade will address. Love the old-school GUI approach, like previously in NetNewsWire 3, which used to be my reader of choice. Not anymore since version 4. Why? I just skim over the headlines, just a couple of seconds max per feed, and if I find something interesting, I will read it. If I miss something, it doesn't matter. Apps like Reeder and NNW4 look neat, of course, but their GUI is obnoxious, not made for speed and power users with 300 feeds, just for shiny appeal. So I'll stick with Vienna, even though it's not perfect. What it needs: better memory management, new coding for snappier behavior (e.g. shutdown), per-feed preferences (refresh rate, keep old feed entries etc.). Just take a look at what you could do with your feeds in NNW3, apply that to Vienna, and I won't complain anymore. ;) One big issue, though: on older MacBookPro models Vienna will force the machine to switch to the discrete NVIDIA graphics card. That's a no-no, if users like me decide to use the integrated Intel graphics card, for reasons of battery-life, system stability etc. You can't manually switch to the integrated graphics card, if Vienna is already running. You need to quit Vienna, then switch from discrete to integrated, then launch Vienna again. Not cool.
