I do feel it's a bit distracting from the content for me; not every picture is gif-like, and I found myself scrolling to animated ones. I'd like to know how 'average' people would like the content presentation, from a reader standpoint, not a hacker standpoint.
I thought it was pretty tastefully done. It could certainly be abused as an effect, but overall I think this is what 'newspapers' are going to look like in the decades to come.
