Levels of awesomeness of what you can do with your presentation/slides:

  1. Not awesome: do nothing.
  2. Average: post your slides on something like Speaker Deck.
  3. A little awesome: make slides for the web in the first place, so they work on the web already.
  4. Very awesome: redesign your presentation for the web.

Scott Jehl just did this for his talk Delivering Responsibly and credits Frank Chimero (e.g. The Web's Grain) and Maciej Cegłowski (e.g. The Internet With A Human Face).
