When you have several platforms and confuse where are you going to post the thing you want and posted it in #nostr instead.
Discussion
I think the first tag on your post, is where your post is automatically posted to.
All right. I'm confuse of another platform though. We have x, fb, why should I choose #nostr?
I think because there are no other platform that offer the same experience as what a social media should be.
Another platform most of the time is just about ads and pushing trend across all of its user.
