Unrelated: Why are people familiar with Hacker News (e.g. the Docker folks) still using slideshare.net? That site feels like it's stuck around 2005. I thought everyone here knew about http://slid.es by now -- its UX is far superior.
I think http://speakerdeck.com/ is even better. IMO the UI is very cool and the entire site very easy to navigate; I actually find it hard to believe it's not a very popular slides sharing platform.
