On the contrary! You need to post links to these articles.
I want to read all of those articles.
I absolutely love the history leading up to and around the first world war, I've read a good portion of the issues of Punch from those years. But a headline is only enough to arouse my appetite without bedding her back down.
Well, you can find the articles by googling the headlines. These are all from the New York Times and you should find the first result is a link to a pdf article there.
The subject of your headlines is critical in my opinion. European news, or Americain centered, International? Popular news? Headlines that turned out very wrong, etc etc. There are so many subjects...
They're from the New York Times. The focus appears to be in order NY, America, Whoever America Is Currently Fighting, Europe, and the rest of the world. Plenty of amusing missed predictions (e.g. VESUVIUS MORE ACTIVE.: Mr Burlingham Says Volcano is Preparing for Another Eruption. - 01/13/14). July is going to be interesting....
Nope. If it was curated it wouldn't be much of a bot. That's how most bots are, the owners just retweet the really good ones.
One idea would be to focus on certain keywords, but you'd miss a lot of interesting stuff.
I don't know if I agree on your percentages though. In the first 3 days, I read stuff about eugenics, Shackleton, a woman declaring martial law on a town (first time martial law had been declared since Civil War), etc.
Aaannd my headlines-from-1914 bot has 11 followers. tl;dr I suppose.
