Ask HN: Should a User Subscribe to a Blog

Many platforms have a way in which users can indicate that they would like to be notified about future content of a creator. What is the best equivalent for independent blogs? I can think of four potential ways to do this, and none are without downsides: - RSS or Atom: high setup cost for user due to no builtin support in browsers. - Web Push notifications: at least in Firefox, push notifications only appear for a few seconds and then seem to disappear forever, making it likely that the user will miss the notification. Also requires custom software on the server-side — I'd be curious to know if there is anything ready-made for this. - Mailing lists: potential concerns about spam — there is no secure way of unsubscribing. - Relying on a platform, such as Twitter and Mastodon: low specificity. Potentially off-putting due to off-topic or low-effort tweets. Am I missing something? This seems like an obviously desirable feature, and yet there's no obvious solution. What's your opinion on this problem?
