Cool tip I found online: you can access a Mastodon account’s RSS feed by appending “.rss” at the end of its profile URL. For example, to follow @Gargron@mastodon.social, you would add https://mastodon.social/@Gargron.rss to your RSS feed.
This is great, because it means I don’t have to create a Mastodon account to follow what people are saying on there 😊.
