Youre welcome. So many clients (altough nostr is still in an early phase) support following hashtags: to do this, you need to search in the searchbar for global messages with the hashtags that you like: for example, #homesteading #bitcoin #linux #nostr or anything else. There will probably somewhere a button to follow this hashtag, so if you find enough nice content, you can follow it and those messages will be in saved in your local feed.
