This look-alike client struggles to show me messages in real-time. It looks like they only get pulled down in big chunks every few seconds. It also fails to scroll the new messages into view. I don't remember these sort of problems in IRC clients or IM programs of the 90s (though there were many other problems).
In a way I guess it paints the irony of modern computing, where we have several orders of magnitude more in computing power and resources, but that has only enabled us to keep rushing out perpetually unpolished, unfinished products.
It's still a bunch of fun to see a bunch of strangers talking completely unfiltered nonsense in a rudimentary chat room, though!
