I personally don't think anything needs to be sacrificed.
(If, perchance, you're one of those whose eyes are offended when you witness capital letters being for emphasis, rather than the much more esthetically pleasing finely crafted prose, kindly avert said eyes from the following. Thank you.)
We have a LOT of space to play with, we have a LOT of materials already, and we have a legion of capable individuals with talent, skill and vision.
There are some things about our current space that are working for some, but possibly not all of our members. I am 100% confident that what we have at our disposal is more than a sufficiency to meet every concern and desire that's been raised.
We don't need to give up metal working, wood working, classroom , electronics, lounge, or sit in comfy settings and hackery about space.
We DO need to come up with a set of goals for what we want at the space, and what kinds of places we want at the space.
This, in my opinion, should come before deciding what specifically goes where, or how big each area should be, or who gets to do what when.
I say this even though I have my own specific ideas about what should go where. That's great, I like my ideas. Your (all of you your) ideas about what should go where are also important to me.
I believe that once we have a list, on a real world big piece of paper, of all the various types of activities and spaces we want to have at the hack factory, we can start figuring out what should happen where, and when.
I haven't taken any classes at the space yet, but the ability to have classes, and space for it, is important to me.
I haven't spent any time sitting on a couch relaxing and listening to music or watching something visual at the space, but I want that to be possible.
I've spent a very small amount of my time sitting in the classroom with other people around me tinkering with non dusty non woodworking projects, but I do want to be able to. JWB has described this activity and setting so well that I'm not even going to try.
I haven't spent any time with a soldering iron in my hand yet, but I'm going to, by golly. I'll need to if I want to build my army of killer robots. (You might think I'm kidding, but I'm totally serious. I've had visions of autonomous ground combat bots going through my head for a looong time.)
Nobody has asked for a swimming pool where the woodworking space is. No one has asked to throw out all the computers so we can replace them with whatever tools are needed for backwards underwater basket weaving. (Scuba gear, mirrors, and some cane working tools, I imagine.. maybe some rebreather gear?)
As we move forward on making our space better, I would ask that all of us listen, talk, participate in the discussion, and know that even though I want escargot, you can still have bavarian cream pie.
