- For coffee, I learned people in the know are after 24/7 changes in the commodities market.
- For worldwide airport news, well, I don't think there is much of a market there (though I would regularly capture 30-50 pertinent articles per day).
- For Brazil news, cultural awareness is nice to have but in order for something like that to be needed, I would think the focus would have to be Business, and very specific (in fact, I played around with making newsletters like this).
- For Brazil tech, I think it was too early on in its development because there were only around 10-15 items per day.
There's a final component I failed to consider with the first two newsletters above, I had no product dev, no one on the inside to say "hey, focus on this aspect, that's what people need."
