If facebook were smart they would acquire twitter or yelp or snap. They need to own some more social outfits to round out their portfolio and build a stronger position in the world. Not that I think snap is great, but put it under facebook and their sales and tech teams could probably pour some fuel on the fire.
To stay on topic - Tesla will replace FB in FANG -- > TANG
Facebook already tried to acquire Snap. Upon refusal, is trying to destroy them via Instagram stories.
Also, I don't have a particular dislike for Zuck but was funny to see him try and clown on Elon. I mean wtf...
Elon - Going to Mars.
Zuck - Released version 2.0 of Myspace.
