Github has a proven business model.
Twitter is an indispensable communications medium that has more than 1 use case (read news, talk to friends, overthrow a government, etc). Thus ads makes sense (and I would even pay a low, yearly fee to keep it around).
Snapchat is interesting, but $100 million interesting?
