@op, typing from my own personal experience, I really don't understand what the rant is all about, I've been a user here since 2016, and though sometimes, the forum seems slow but it's always due to my poor network signal or connection, and even at this, it's never been as bad as you make it seem like, there are many times that my network signal becomes so bad that I loose connection to several other websites but surprisingly, my connection to this forum is still maintained.
So I personally would say that, if you are experiencing this problem, then check properly and see if it's not from your end.
