Hello and welcome to nostr, the freedom protocol that you control your data and take it with you to whatever platform you want. Damus is a social media platform that runs on nostr and IMO one of the best, but there are also long form blogging platforms, wiki platforms, streaming, video sharing, podcasting, encrypted messaging, marketplaces, and more all running on nostr and you can take your public and private keys from damus and use all of them while bringing your followers, follows, and previous data with you.
