I’ve been testing to see which feed readers support authentication sufficiently to enable you to log in to LJ somehow and hence see LiveJournal protected posts in your web feed reader. Do work, by prior login: Sage. Akregator. Opera*. Safari*. Do work, by modifying URL: Mozilla Thunderbird. Do not work: Google Reader. Bloglines. Other people report that they work: FeedDemon. NetNewsWire. *Not tested, but I’m pretty sure they do because the feed reader code is part of the web browser.
