As Scoble, Jason Row, and, of course, Nick mentioned, FeedDemon 1.5 has been released into Beta. It looks like the biggest deal with version 1.5 is the integration with BlogLines. This new feature of FeedDemon allows FeedDemon users to synchronize subscribed feeds with BlogLine subscriptions. Thus, you can synchronize feeds among multiple computers without having to re-read a bunch of posts. This was an issue with me because I often work on multiple computers and the utilizing the cache feature by moving data using a thumb drive just wasn't exactly what I was looking for. I was looking for an even easier solution because...well, because I'm lazy :)
Nick didn't stop there. He's added a lot of new features in this release. I've been using FeedDemon for quite a while now and have been very pleased. It's well worth the $29.95 if you subscribe to many RSS feeds.
