do you not? have you heard of metcalfe's law? the value of a network is proportional to the square of the nimber of users. so too is the difficulty in supporting & running the vastly more interconnected network.

video is easy as shit. yeah you need bandwidth/transit. but people join & leave infrequently. they are low impact consumers: them joining does not change the total load significantly, it's only a little more linear growth. whatever to that, irrelevant.

twitter is a vastly wider & more connected not-so-micro- cosm. if there are 50m followers, and they tweet, the burden of rippling that event out is huge. tracking & making visible every fav, retweet & reply further escallates the difficulty by more deep deep orders of magnitude.

it's laughable to me that you would try to say discord has a higher event rate than twitter. first, i think thats horseshit, totslly absurdly flat wrong in extreme if you count favs, retweets, et-cetera. but more so, event rate is pointless. it's event receievers that actually count, that matter. and the little intranet micro-world discords are, by any measure, totally pointless & irrelevant by compare versus the all-connected fabric that is twitter. discord has no scale, is itrelevant entirely, in how far it has to spread any given message/event. discord is a large number of the tiniest little fishbowls; it compares not at all to the sea.
