I'm another that misses the app. I find now that I visit less frequently, but I'm more efficient in my viewing. I can't use the mobile view of the app (it's bad), so I use a computer/web browser and open all the new posts using the method Gumby posted and browse through the ones that I'm interested in. I find that I get through the posts quicker than I did with the mobile app, so I guess that's a plus.
What would be cool is if I could click a button and it'd automatically open all the 'new post' threads into a new tab where they left off. Clicking that right arrow for each thread takes time and is a bit of a hassle.
