Mark Dominus writes "Lightning talks are brief (5-minute) talks that focus on a single example, idea, project, or technique. Lightning talks do not attempt to cover all aspects of their subject matter, but rather to present one facet of the idea clearly and succinctly. To submit a proposal for a lightning talk, please send your proposed title and an abstract of up to four sentences to osc-lt-2005-submit-perl@plover.com . For more complete information, visit the lightning talks site. Thanks."
