I'll probably be back to check out more of the videos, but definitely not because of the site. If the editing is good, YouTube is just fine, otherwise SlideShare plus an audio file is just perfect.

Although slideshare is not as bad as infoq by a long shot, it's not very useable (or fast) either. I much prefer speakerdeck.
A full transcript with interleaved slide images takes a few minutes to read at most, and lets you control the pace of information absorption. A video with slides, especially when you cannot 2x the talking speed, is a painfully slow data transfer method.
Video + Slides = analog modem
Transcript w/ embedded slides = Google fiber :-)
Of course, if you're into audio books instead of reading, maybe you consider that a feature.
// I push video for a living. It's great for visual explanation like DIY instruction (e.g. woodworking, swapping RAM on a Mac Mini), emotional content, personal story telling, etc. Systems architecture is generally not in one of those categories.
I don't have a solid block of 40 undisturbed minutes to listen to a talk. Give me a transcript and I can read a paragraph here and there as I do other things at my own pace. I might have ten minutes here, ten minutes there. I don't want to be constantly pausing/unpausing the video, or worse - switching between the video and my music.
Plus, if I concentrate, I could read a 40 minute talk in 20 minutes or less.
Basically, when I'm reading, I control the pace. I rarely watch videos that are longer than about 5 minutes (that aren't entertainment, which is entirely different).
