In reply to Miroslav Glavic.

WordCampers are spoiled by the $20-40 fees associated with WordCamps. Price out other conferences and then be grateful for the financial support the WordCamp Foundation provides for the regional community-based events that we've all profited off of....

$50 for a 1 day conference w/direct access to the software developers is really nothing to complain about.... but again... it's hard when barrier to entry into the WordPress community really costs very little and the return on that personal expense is huge. That's atypical in ANY industry.
