I miss having a view that shows the newest posts. Checking every thread isn't very practical. So far, the best workaround I've found is to click on the little notifications bell icon in the upper right of the page. If you have notifications turned on (I think they are by default), you'll see a list of all the latest posts and comments and can visit each one from there.

There's an app for the site?! Not that I need another app on my phone but that's awesome!
