I installed the latest release build of Syndirella at home, and it’s working fine. I also just downloaded the latest daily build and put it on the computer where the latest release wasn’t working, and it works, too. I haven’t used NetNewsWire, so I can’t compare Syndirella to the gold standard of RSS readers, but I’m pretty pleased with it on its own merits. There are a few odd things about it, but that may just be my unfamiliarity with it.
