Bloglines vs. Google Reader

Since I'm already a regular user of Google Reader I thought that I would take a look at the feeds that I already subscribe to in Bloglines. The first thing I noticed was an import/export feature in Google Reader that saved me from manually resubscribing in Bloglines. Very handy! Almost immediately, I discovered a significant difference between the two services. In Google Reader I can click on a feed and it leaves the individual posts unread until I've clicked on them. Bloglines, however, marks all of the posts as read the moment I open the feed. I do see that there's a "keep new" function, but I often have several posts waiting for me (Project Play is not the only thing I'm behind on!) and it's just easier for me if they are left unread until I select them. Of course, it's entirely possible that there is a setting to change this and I just haven't found it yet! For now, I'm sticking with Google Reader.
