To be fair, selling food and toys to childless yuppies was at least a facially rational business model. I have to admit I'm impressed Twitter has managed to find greater fools to fund their shenanigans. I guess being the President of the United States's favorite social network is bankable.

And has never shown a profit.

> Whatever it may be, it is not pets.com

What if the runways are just longer this time around?
