Okay, let's get down to brass tacks here (I don't know what that means).
The latest thread to each forum needs to be in bold so as to standout from the rest of the print, to be noticeable above anything else.
I am always on this site from my phone. Forget about desktops. I don't even want to bother grabbing our Chromebook. My phone is always with me. So this discussion had me curious, because I'm always on a mobile view. I took a look tonight, and I have to say I really like it.
I'm on XDA Developers a lot for tech discussions, and they made a move to this kind of layout a while ago. It seems fresher than your traditional linear home page. I suspect a lot of forums are trending this way.
