A look at the design of these forum speaks louder for it self... Saying you might not enjoy it using some devices...
When writing or reading I guess you know how it is with your android....
I didn't try it until reluctantly I decided to open bitcointalk.org on a computer system. Over there the difference was alarming compared to using your phone...
As much as it can be used on phone it is best with a computer system... I even noticed that without a computer system some challenges or updates one will not be able to follow up...
The forum design was fine in my opinion and the admin prefers it this way, I remember they removed GIFs in the forum, just to make it this look like just text, and everything looks kinda of old. But functionality-wise this is how a forum should be since its all about the information you are meant to be reading and typing, I don't have any issue with the design for sure and it does its job great, I don't think we need to add anything on that, it also makes it last for a long time considering the storage of the data if we are going to include a lot of GIFs, photo, video and put it here that is going to take a huge space for sure.
I gonna have to agree, there were some issues when it came to smartphone use because of the small size of the screen, but you could still make your way on it, it just a matter of what you're going to prefer using, there are a lot of members that prefer using a smartphone when they are using the forum, Personally I prefer using desktop or laptop because of the huge screen, It was just difficult to navigate on a smartphone but still doable anyway.
