It’s not about having a serious alternative, what twitter does can mostly be written by like 10 people in 3 months. The problem is scaling it to be big enough while eating that cost until enough people start using it.
AND the advertising budget.
There’s no real way to break into that now without a ridiculous amount of investor capital which investors are gunshy in offering for shit like this right now.
We don’t need an alternative, we need the next generation and I hate to say it but it might just be Discord if they get their shit together.
