There was a fire a few blocks up from us. From our fourth floor apartment window we had a pretty good view (though as you'll see in the first video not a very good live streaming view, the shooting flames don't come through at all!).
I've been dabbling in safe live streaming (such as that walk along the Buffalo trail) but this gave me an opportunity to try live streaming real breaking news. My camera was there before some of the fire trucks.
I alternated between Facebook's relatively new LIVE feature and Twitter's Periscope, trying to sort out which made the better sense in the event that someday in the future I'm not shooting the smoldering aftermath of a building fire but perhaps the landing of space aliens in the woods.
I don't want to get into a ramble here about which turned out to be better for the cause because I haven't processed the experience yet well enough to say. If you watch one of the Periscope versions linked to below (the second one I believe) I do some out loud thinking that might give you an idea of my impression at the time. Offhand I will observe that both applications allowed me to live stream instantly to the world within a minute. When I am through analyzing it I suspect the judgement will be based on things like post-shoot portability (how well can it be shared), findability, and other things like that. Mechanically, there just wasn't much difference.
More to write about this later.
