No, it just tells me there's no new posts. I think it has something to do with the way cookies are saved across browsers. Before I left this AM, I clicked it at home and it showed all of the posts that were new since my last visit, but I didn't actually view any of them. I clicked it at work and it tells me there's no new posts to view in the past 24 hours. It's starting to update now from the time I've clicked it to new posts after that.
