Rich Mironov, organizer for the Silicon Valley Product Camp 2010, says that the pre-registration is closed at 960 people. Zounds!
The event is still open for any and all product managers and product marketers to attend. In fact, because 960 people have already registered, you definitely should attend. Last year's P-Camp was jam-packed with useful information, and it provided an unparalleled opportunity for PMs to compare notes. Attendance last year was a fraction of this year's pre-registration number, and the value of the P-Camp only increases with numbers.
Look forward to seeing you there. (And you'll have my gratitude if you vote for my afternoon presentation on the strategic role of PM.)
