YAPC is "yet another Perl conference", with apologies to The Perl Conference. This is an inexpensive (US$ 100 for 3 days) conference with its roots in the Perl Mongers Perl users groups.

While The Perl Conference plays an important role in the Perl community, there are some things that fall through the cracks at such a large, relatively corporate conference. Attendance fees of $1,000 or more are prohibitive, especially to students (though there are deep student discounts); furthermore, the conference is on the West Coast, incurring travel expenses for those in the east, on top of the conference expense. YAPC is driven from the bottom up, organized by and for Perl users -- a grassroots conference.

YAPC began as a smaller, regional version of TPC in the Eastern USA, hosted byCarnegie Mellon University, and has become a series of conferences held in multiple areas of the globe, all aimed at bringing together the Perl community in an accessible manner.
