Looks like Twitter has a good eye and an appetite for risk.

I agree, both Vine and Periscope seem to be good value.

I wondered if they bought many busts for equivalent valuations, fortunately Wikipedia has a list:

And there's a list of companies I haven't heard of, no idea if they were good buys or not (Gnip, Namo Media and others).
