Yes, please-oh-please!   Even though this is a volunteer-driven effort, we have a few hard costs: food and t-shirts.  (Yahoo has graciously let us use their wonderful facility again, which chops the cost dramatically.)

If your company can be a sponsor, for as little as $500, we'll thank you publicly, promote your logo/link, and include one of your handouts in the registration package.  See Sponsors page linked at left.

Send a direct tweet to @RichMironov if you have a possible sponsor.
Most Product Camps have been very successful with "dot voting" where everyone gets some stickers ("dots") to stick onto the talks/sessions they like the most.  Organizers then just count up the dots to see which sessions win.
With 500+ likely attendees, we want to avoid a mob scene so early in the morning.  We want to get the MORNING agenda picked a few days in advance, and still have "dot voting" for the afternoon as everyone arrives.
