I have an organic growth marketing suggestion: - Laptop stickers. Start with your own laptop. See if people come online and talk to you. If they do, ask them if they'd like a sticker too. Tell them that they can gift a sticker to a friend from the website.

- Also, a desktop app / plugin for Slack / Discord / something else. I don't pay attention to my phone when I'm working but I am on a few chats that I check on and off on my laptop.
