@MadAsAHatter @rufustheduck I think the level of engagement with new posters is driven by what they have in their profile - I know I don't follow back anyone who hasn't filled in at least some basic information so I know what to expect from them in my timeline.
It is *very* different here to other social media platforms: when I started, I followed everyone who posted anything vaguely interesting, then whittled down my follow list once I'd work out what I wanted (and yes, cat pictures featured in that list: send them!)
