I think we all have grown disappointed in the devolution of SlideShare. I'm so excited to see my friends at Ordered List have done something about it. Over a year in the making, they have raised the curtain on Speaker Deck.
We promise that we will never clutter your presentations with ads and we will do our best to keep it free and simple to upload and share your presentations without the mess.
I'm a big fan and am using Speaker Deck to power the talks part of this site.
