Someone asked me what is a "Lightning Talk" ?
Lightning Talks represent a much smaller investment of time than a full presentation, and offer you the chance to share your "neato" thing without the heavy commitment of a real presentation. Lightning Talks should emphasize your single biggest bang-for-the buck idea quickly.
Use this as an opportunity to give a talk for the first time, or the first time on a new topic. For a Lightning Talk, slides or documentation are not required, but if you do decide to make slides you only need a few.
Lightning Talks may just be interesting or useful websites that others should know about.
