WeWork does a lot of pretending about this, but it mostly takes the form of a social network web application. In the space itself, there definitely is not a norm of networking with the other randos at desks. The place has more of a library vibe than a makerspace vibe.

I've been to both WeWork spaces in Austin (where I live) and the one downtown hosts a lot of events that I believe WeWork customers have priority at them (discount tickets and other things).
