Social networking is just one entry in the long list of Google's failures, many of which were successfully executed by smaller companies:

* Chat. Google has tried like 4 or 5 different times to do chat and ultimately lost out to the likes of WhatsApp, Slack, Messenger and others.

* Location/business Reviews. Despite having Maps, google still has yet to really come close to unseating Yelp in this arena.

* Wearables. Google Glass completely failed. Android Wear is well on its way to the grave. Fitbit, Apple and Samsung have all succeeded in wearables over Google.

* Augmented Reality. Remember Google Glass?

The list goes on. My point isn't that Google can't do anything right — that's obviously not true. What I'm saying is that Google trying something and failing isn't really a good argument against it being a viable idea.

Facebook's brand is ailing right now and I think there's growing concern about the way Facebook has been optimized to dominate the user's attention. There might be room for a social network that tries to be something much more minimal than what Facebook has become.

When google tried to go push '+' they needed the people to forget about the data, messages, pictures and everything else that was on facebook. That burden was a bit too much.

GDPR requires facebook to provide users with their data in a machine readable format. So that competitors could write migration scripts and there would be no such lock-in. Makes it easy to switch platforms and bring some competition into the space.
