I also tried one of my own articles, a post I wrote in 2018 about Elmish in F#. It figured out it was me based on the date I said I started using F#; a mention of some Fable Mobx bindings I had written (I didn't say I had published them); an "affection for F# and Dart as a secondary favorite — an unusual pairing that shows up in his other writing"; and the "casual conversational register" that matched my writing style. I'm not surprised it could identify me, just surprised by what tipped it off, I guess.
