Re: Straw Poll / Proposal for San Francisco Area mini-meetup

That's a little surprising -- sometimes I feel like I have the Inverse Midas Touch when planning informal get-togethers, meetups, and parties. And yet plan I try. I think for many people, making money for even a single person keeps the nose to the grindstone. If I had my own house, I would host the ...
