Adobe Air: Sure you can export your RSS feeds from Google Reader and import the feed file into desktop RSS reader for offline browsing. Scoop takes offline browsing a step further by allowing you to not only read your feeds but have them remain synced to your Google Reader account. Removing and tagging items in Scoop modifies the feeds in your Reader account as well. The interface is easy to use and includes most of the commonly used keyboard shortcuts from Google Reader. On the downside images are not currently downloaded for offline browsing, so if you've synced and now no longer have internet access you're out of luck until you're jacked back in. Scoop can be used independently of Google Reader, with manually added feeds, but it's Google integration is where it shines. For an alternate method of accessing your Google Reader feeds offline, check out Google Gears and RSS Bandit. Scoop is freeware, cross platform, and requires Adobe Air to run.
