I often see people asking their friends and subscribers in social networks something like «Tell me what to write about so that it would be interesting and useful for you?» This is very, very dangerous. But they also have (one) benefit.

My opinion is

1. In general, no one cares. This is a well-known truth.
2. What is actually interesting to read, people don't really know. The most resonant posts are about things that are not obvious «on the shore». People will say they «need faster horses» 🐎 
3. People are terribly bad at extrapolating an event and bad at predicting the future. What they will want in an hour, tomorrow or in a year - they can never know.
4. The feedback and reactions you might expect to receive on your posts will not be what you expect (energetically and meaningfully), and the feedback loop will not be closed.
5. If you do not receive this feedback for some reason (the post did not work, the post did not fall into coverage, etc.), you will blame yourself for the failure - and this is not a failure at all.
6. The truth is that you won't be able to write authentically, interestingly, and energized by the process by writing for someone other than yourself.
7. You are killing yourself with this, contact with your own body and inner world for the sake of hypothetical feedback (by the way, what kind of feedback are you doing?)
8. This is your process and yours alone. Get off others, take care of yourself 😂

But! Letting yourself catch your breath, there is also a benefit in this matter: people can reveal some of your hidden or shadow features that they like about you. This might be a good gift for you. But you need to go into this matter with the pure intention of research, that is, out of curiosity.
