Apart from ProductHunt, on which channels are you or is your startup also active?

As a founder, it often feels like you are not doing enough - especially in marketing. Some ‘experts’ suggest that you need to have a presence everywhere, while others argue that focusing on fewer channels but using them more intensively is the better approach. 🎯 Personally, I find the strategy of fewer channels more sensible. Now I’m curious: which channels do you focus on, and why? 👀
