Like I said earlier, you are using a crap browser so its not the fault of the site It can be Gecko or WebKit or <insert-flavour-of-the-season> but if the UI isn't integrated well with the engine, its like applying lipstick on a pig

I use FF on droid and yet don't have any problems viewing, posting or even moderating the site. I double-click on an area and it zooms in well there unlike what I suspect you are suffering on Jolla's browser which may be similar to the oddities exhibited in qmlmozembed.

Of course everything can be improved upon but its nowhere as bad as you make it out to be just because you have sub-standard tools
