I was recently quoted as saying, I don't care if Instagram has more users than Twitter. If you read the article you’ll note there’s a big “if” before my not giving of said shit. Numbers are important. Number of users is important. So are lots of other things. Different services create value in different ways. Trust your gut as much (or more) than the numbers. Figure out what matters and build something good.
When you are alone for days or weeks at a time, you eventually become drawn to people. Talking to randos is the norm. I’ll never forget the conversation with the aquarium fisherman, forest ranger, and women at the Thai market. It’s refreshing to compare notes on life with people from vastly different backgrounds.
