First, we intend to bring sync to future versions of NetNewsWire. It's too soon to go into details about this, but you should know that we recognize how extremely important it is and that it is a top priority for us. Second, even though we've been quiet about it, we have been working on new versions of NetNewsWire for Mac, iPhone, and iPad. We have some great new features and a modern design that we can't wait to show you. … As far as sync is concerned, we knew we would likely need an alternative to Google Reader as early as last year. Fantastic news.
