I've been building an app to reduce the noise in human conversations and recently I found a similar app that started a year before me. My instinct is to email the other founder and ask him "Hey how's it going? Can you share what you've learned with me?" but I wasn't sure if putting myself on their radar can be a good or bad idea?
Curious what the HN community think? What's your experience in your "relationship" with your competitive peers?
