Shared Studio Spaces

This is something I've been thinking a lot about.  The fact of the matter is, as much as it's awesome, I don't work my best from home.  I want to be able to "go to work" in the morning, see people, do my thing, and then come home.  There are too many complications and distractions working from home, and too few opportunities to participate in the world as a human being.  And I know of co-working spaces, to be sure there are loads of options in San Francisco, but having visited a bunch of them, there aren't any just right.  I've always had a fantasy of starting a shared studio space, a small one, not a big vaulty warehouse style thing, maybe a half-dozen or like 8 people, not necessarily illustrators just self-proclaimed "nerds."  I love the idea of coming to work and seeing my (sort-of) co-workers, and then getting to "get down to business" with work that really matters to me.  We could have a little kitchenette, and a hangout area, and could ask each other if this-or-that comic sequence makes sense, or do you have an extra eraser, and have movie nights and stuff.  

Okay but the point of this isn't to go off on my weird fantasy thing.  I've always stopped myself from looking with any actual intent because the amount of effort into the "businessy" direction intimidates me terribly, and it's not like I have this huge untapped wealth of time (not to mention funds) right now to get something like this going.  So there are two sides one of which is: "Leela this is a fantasy, you don't have time for this nonsense."  The other is "Leela you are 22 and have more optimism and energy than you ever will again.  Probably this is the PERFECT time and frankly you've been having a streak of luck so why the hell not just look into it?"

The actual point is to ask you guys about your thoughts, experiences, opinions on shared working spaces.  For those of you who have worked in a shared studio or co-working space- what was good/bad?  Would it have been better/worse if it were specifically marketed to designers and other creatives?  For people who already work from home- is this an option you would consider?  Could imagine yourself enjoying?  Knowing that the usual going rate for a dedicated desk in a co-working space is between $425-500 a month, (in San Francisco, anyway, and trust me I also find this absurd,) what can you see yourself actually able to pay?  And while I'm at it, is there anyone in San Francisco who is looking for just such an opportunity?  

Can't say anything will come of this, alls I know is it's been on my mind and I value the input I can get from you all, so I might as well ask!!!
