Most Nostr clients have a re-note to "repost" someone's note on your account. Or you can use the share button on many clients to share outside of Nostr. In Amethyst on Android you can get an njump link. Which is great for sending to people who don't have Nostr and don't know what it is. https://njump.me/nevent1qqswdv8hr85ucv5hwjwu0wrrg4m8s822ue6er9s35r7q6uuw83snz5spz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsyg9ee6hwkstc54y73vzhpu6gkt92f0hcjvl7xv3agh3cwhqpjxdzcgpsgqqqqqqs3shvy9
