Your first Blurt post does not need to be complicated. A short introduction is often the best way to start.
Choose a frontend
You can publish through Blurt.blog, BeBlurt or another frontend. The frontend is only an interface to the blockchain.
Write a simple introduction
Say who you are, what topics interest you and what you want to publish about.
Use tags
Tags help other people find your content. If you post in Polish, use polish. For English content, use topic tags that match your article.
Reply to comments
Blurt works best as a community. Comments are often the fastest way to meet active users.
