Like you, I'm not on Twitter,
@quasar987, but are intermittent interruptions of 'something interesting' based on other people's assessment a service you would value?
My alternative is to routinely plug-in "science news" to my browser, and also regularly review sites like phys.org and Science Direct, to see what's going on. It is considerably less intrusive than Twitter in distraction and personal data, and you can hone the topic, so "ev news" for example to just get electric vehicle updates.
I guess it depends on whether you feel you are missing something now, and if you do, you can test Twitter and see whether it fills the gap.
In terms of who to follow, if you're already listening to science podcasts, you're likely able to compile an initial hit list from guests you find engaging, but it probably makes more sense to follow publications than people, at least at the start unless you already know your specific areas of interest and are comfortable ignoring others.
