Would higher altitude not correlate with colder, gray, gloomier (highly scientific term) winters?

I gotta stash this one away. I often refer to the disaster of 20th century health science as scientists repeatedly gathering a single point of data and then drawing a line (or hyperplane) though it, but this is a great article clearly demonstrating an example of that, and how plausible it all seemed at the time.
(Not that it's a trend limited to the 20th century. But it seems to me to have been extremely bad in the health area in that time frame. Not uniquely so necessarily, but quite bad.)
I imagine the 20th century was the worst time for it because we had more sophisticated data collection and analysis methods, but failed to recognize our own inadequacies when using those tools to draw conclusions.
Kind of like social media algorithms today.

Congrats!
How do you automate screening the sky?
Do you have robots that map stars, diff the images, and send an email when the diff has a new spot of light?
How frequently does the sky get fully screened? Could there be events fast enough that we don't detect them?
This paper by one of the team members has more detail about the process used to narrow down the search field to a list of galaxies and identify possible locations of the event:

Apologies, I'm not one of the researchers involved in the discovery. I'm just the web developer who built the announcement site for UCSC. Ryan Foley will participate in a Reddit AMA tomorrow (Tuesday, 10/17). I imagine your questions might get answered there.

Can some astronomer or physicist actually make an image where the source is marked? All I see is some stars and a galaxy which is basically and some textual explanation where I should look for it.
There are before and after comparison photos here:

A team from UC Santa Cruz used the data from the Swope telescope in Chile to locate the source of the gravitation waves and observe the light from the event. The data provides evidence of how gold and other heavy elements formed in the universe.

I think this may just be another instance of the coconut affect.
I once had a job making ice cream and it bothered me that I had to add yellow food coloring to the banana ice cream. We used real bananas and didn't add banana flavor. But I was told to add yellow color anyway.
It is not in Facebook's monetary interest to identify or remove fake or questionable news from our news feeds. By it's nature, fake news is emotional. It causes an emotional, gut-level reaction ("OMG, must like and share this!") that promotes virality. Virality === $$$ for Facebook. I imagine they have already experimented with news feed filters that reduce noise and I'm sure the result was reduced engagement. As long as Facebook profits from attention, we should expect them to be tepid at best about any change that reduces their share of our attention.
