We recently started one in Berlin (https://forum.effectivealtruism.org/posts/NnrHvJALEKH4Ykzyt/introducing-teamwork-an-ea-coworking-space-in-berlin). tl:dr I'm very happy with the decision. Happy to chat about details.

Have you talked to the other people running Coworking Spaces? There's one setting up in London, another in Berlin + Bay Area has had this for a while.

We run a coworking space in Prague. 

Very interesting idea! I may be preaching to the choir but the importance of a physical space to not only work but also gather for social gatherings (official and otherwise) is a key feature to robust community building. So I am super eager to see how it turns out! 

I am a student at Cornell up in Ithaca but travel to NYC once or twice a month and would love to have the ability to stop by somewhere where a ton of EA's are doing working, and chatting for a cup of coffee and a good chat! I have had the chance to meet with folks from other New York State and Boston Universities. It seems that generally, a lack of physical spaces for people to meet inter-collegiately seems to be a major point of frustration for many of us EAs. 

I'd be interested in this if I moved to NYC. I'm currently at the very early beginnings of preparing for interviews and I'm not sure where I'll land yet so I won't answer the survey. Definitely a great idea, though. The decently-sized EA community in NYC is one of the reasons it's my top choice for a place to move to.
