Personally, I've observed (via the voting mechanism and commentary) several different cohorts of people visit HN throughout the day. You get a real sense that opinions are regional and tribal. Europeans in the early morning, then east coast and flyover states, and then brace for impact when SV (in particular Googlers and/or pro-Googlers) pile on. It's fascinating.
No science here, absolutely, but I have had great success so far predicting in advance what the voting pattern is going to be on a comment I make. I treat it a bit like a sport.
I installed innocent piece of Google SW on my Mac, Android File Transfer [0]. Immediately it tried to install several launch agents, driving BlockBlock [1] crazy. Uninstalled right away without opening the app.
People tend to subconsciously forget that Google is an Ad company by 85% of revenue.

That's not magic mate, something needs to monitor for your Android device being connected otherwise you'd complain that it's not as user friendly as other Mac apps.
