The UI was slow as a trickle of cold honey on my machine. Because it was asking my machine to do more than it was capable of. Normally this isn't a problem.

The UI was slow as a trickle of cold honey on my machine. Because it was asking my machine to do more than it was capable of. Normally this isn't a problem. I use this machine to work on CAD models and while not a speed monster, it is doing just fine. Heck, I can even run Slack on it. Above a certain response time threshold a UI goes from being "slow" to being "unusable" or simply "broken". This isn't a matter of opinion, it is a reality. And I'm afraid that you will have to be a lot more charming and persuasive to make me forget reality :-) UX specialists that do not take sluggishness seriously simply aren't UX specialists in any meaningful sense of the word. I'm sorry, but life doesn't hand out medals for mere participation. (As for the site: I clicked around a bit, but the sluggishness of the site made me lose interest before really grasping what cleverness I was supposed to experience)
