My colleague, @reiver, pioneered native video for the web.
For real.
Prior to his efforts, if you wanted to watch video, you had to install proprietary Flash. Thank God those days are over!
@reiver advocated hard for a <video> tag. Now web browsers natively support it.
Today, the W3C acknowledges his work.
