The idea was to do the update silently, in background (and do not show that Loading… at all).
My own feeling is that when I navigate and use forum actively in more then 10 minutes, it becomes really annoying to see that black “Loading…” all the time.
Every page is loading on the net when I open it, so I do know that it is loading or updating something when I just starting the page, but why must I see “Loading…” message. To me it is ugly.
From my point of view, static content is more readable. Because Discource is primarily oriented for reading, it must look like static and silent, not like youtube or any other multimedia website. Hope it makes sense.
