I dunno, sometimes some relays have poor connections and get flooded by other relays that they bring feeds in from. Mine is connected to a bunch to bring in new posts from a load of different relays (under the Global page) to help start conversations - I hope mine's not slow! 😬
Sometimes profiles just don't even load, so I have to use nak to get them and/or their previous posts, even when following someone. If my profile doesn't load, it's Waethorn (npub1ahd…6ee5) . You can add my relay at wss://freespeech.social/relay , or try the frontend here (uses Soapbox on Ditto): https://freespeech.social
