I will start by saying I really like the design of the site. I find the mobile site really presents the information you want and nothing more.
However I do have a bit of a problem with forever scrolling lists. Is there a way view the posts as pages instead? If you've clicked on a post then hit back it only loads the top posts, so you have to click 'more' a few times to get back to where you were. But even if it did, the back would cause a lot of post titles to load at once which makes the whole thing slow down on the mobile. I'm genuinely not convinced this is a better method of navigating a large list than pages was, but I'm happy to hear if you think it is.
Of course it's all just suggestions and I'll carry on using it anyway!
