Unfortunately not. Notes are stored across relays and there is no inherent way to delete. You are stuck with your mistakes and shit posting.

Yes, you can definitely write directly on the app you using!

The apps I am collecting in this explore page, well most of them at least, have direct compatibility with Nostr so for some content such as long form blogging, you can log into them via your Nostr credentials and then it all Interoperates easily and cohesively.

Can I write/ post it on here instead of specific things?

Good morning and pura vida, Nostr! It's time to stack notes and send zaps! 💜🤙🏻🫂

Welcome new Nostriches! It's great to have all of you join us. Nostr is so much more than a Twitter clone. It's an entire protocol of social communication. This includes blogging or long form content tools, communities similar to Reddit, chat apps like Telegram, note taking / bookmarking apps, and so much more! Welcome!

My main issue with nostr is that it seems like the people here are almost exclusively laser-eye maxis.

When I want to reach those guys, I don’t need a special app: I just tweet on Twitter with carefully selected trigger keywords, and sure enough, one of them will screenshot it and post here and make sure all laser-eyes see it.

Are there some non-laser-eyes here? Make yourself known in the comments!
