I’ve been using NetNewsWire all day today, and have discovered two things about it — one good, one bad.
First, the bad: If you’re signed up to a metric crapload of feeds like I currently am and you set NNW to update automatically every 30 mins, NNW will eat your entire CPU if you let it. I’ve cranked the number of concurrent downloads it’s allowed to use to 2, which helps, but not a lot. I’ve also set it to autoupdate every 2 hours instead of every 30 mins.
I’m also paring down on the number of feeds I’m subscribed to. I currently have 1423 unread items in my feeds, and there’s just no way I can keep up on that much news. I need to finesse the list with extreme prejudice.
Now, the good: My wiki has RSS feeds for the Recent Changes and New Pages lists. I, obviously, subscribe to these. NetNewsWire displays these items beautifully and lets me view the entire diff for each change cleanly and at a glance. I love it. Here’s a screenshot, click for full size:
