The multiplayer cursors are an experiment in ambient togetherness on the web...
...and what I'm learning is that ambient togetherness really doesn't scale to 500 simultaneous readers!
Please use Reader Mode for calmness, and apologies for the noise. I'll work on adding a toggle to turn them off.
btw you may be interested in the code, which you can use/fork:

My blog is a static site, and real-time multiplayer is handled by a small app written with PartyKit (which I am super into).
