You can pay nostr.build to host your content and longer videos. There’s also software you can run yourself, but paying nostr.build or another image host is a simple solution. I believe if you post with primal or satellite.earth they’ll use their CDN.
Thanks! Nostr.build isn’t connecting but my point wasn’t to ask for help (but I appreciate it!). If we want Nostr to grow, and I do, the information you have there needs to be readily available and people who are used to just tweeting can make the information work. crApple didn’t just market and grow well but they had a product and ecosystem people could access easily. I know these are still early days but that is where we need to get for broad adoption.
