Define “boring” here? If you mean “as full of shitposts and memes as Twitter and/or Reddit” then yes, you’re going to be bored on Mastodon. Since, however, I found those very posts boring as all shit on Twitter/Reddit, my feed suits me. A few hundred posts a day on topics that interest me, with about … say … 50% of them being somewhat insightful and/or thought-provoking. (The equivalent on Twitter was “however many posts the algorithm could shovel into my heap per day with about 0.01% of them being even slightly interesting”. For Reddit it was so low I never bothered with an account.)
