While Twitter revenue grew $664M, $1,403M to $2,218M over the past three years, it is going to be a lot flatter than that at the end of this year - and despite that growth they've consistently been losing about $500M p.a ($645M, $577M and $521M respectively)
3,800 people work there - and equivalent cuts last year can barely be noticed on the financials.
The good times are over - they've spent billions over the last few years and not done anything to save them from flat user growth. They really need a wholesale shakeup and doing it over time, like Yahoo did, will just make it worse.
edit: here's a more brutal analysis [0][1]:
> PS. Twitter staff - I am not exaggerating. Look at the young man on your left and the young woman on your right. Only one of you three will keep your job.
