I just use the desktop, I don't like using my phone for forums. Its good to know, and not surprising, that this one has a good interface.
I like to open each thread I'm interested in reading, into a tab of its own. I open all of them, and then close them as I read. Its more time efficient when one has a slow or intermittent connection. I also like seeing, by the number of remaining tabs, how much I have left to go.
