I don't encourage you spending all your time on social media or keeping the notifs on if you're working on something serious. I don't do that personally. Sharing my knowledge on social media is a necessity as I don't have my platform right now, but it also vies for your attention all the time which is against productivity.
Therefore, If you want to know when a newsletter is out, or a podcast episode, or a live session is scheduled, this is the one place. Just join the page and switch ON the notifs for this one page.
I like the fact that in Telegram you can control the notifs at page level on your phone.
