As far as twitter, they unfortunately took a bite of "poison apple" of public investment, and as such are beholden to investors, so must perform (and grow) to ever more higher levels. What would happen - i wonder - if twitter became private again, or better yet some sort of non-profit? What if their platform somehow became the genesis of the new, decentralized web somehow...In other words "phoenix" their way out of this mess by literally -reinventing themselves...If by "reinventing themselves", it might be really more of a major tweak to their operation mode. If twitter - the protocol - as opposed to twitter - the ad/communication platform - reinvented itself in that way, i think i might consider going back and using it; that is, if I'm able to retain control of my own content. Until then, I'll stick with matrix.org (specifically riot.im).
