I love the idea of a list of requirements.
For me, I like the current SudoRoom spaces because of the big common area with a library like space. any future space for work or play for me would have a lovely common room as well.
If any future area has a safe common area that's a layer removed from the street that's pretty cool.
I think it helps a lot with welcoming newcomers, who might feel claustrophic jumping into the SudoRoom right away.
the common area also does a lot to dissolve potential conflicts, as it provides many peaceful spaces away from the sudoRoom itself. noisebridge has a lot of side rooms that serve the same purpose.
I like that the common area is not at street level and that people have to make a commitment to walk up the stairs... but then the common room is like a halfway point, a nice limbo where people can dip in and out of the sudoroom before making up their minds.
I used to volunteer at Rock Paper Scissors Collective and we'd get all sorts of interesting characters, but they have a storefront, so it's a different vibe.
i like the random interactions we have with the Public School. i feel that they are doing the same thing as us in a twisted kind of way.
