I don't know! I do love getting replies~
Not everything needs an answer though. At some point Twitter stopped notifying me about replies from non-followers so if you don't follow me I may not see it. Quite a high number of replies get automatically flagged as potential spam too. I also mute some accounts that I've followed but who tweet a whole lot about things I'm not interested in, or who I struggle to have conversations with because their minds clearly work very differently from mine so I struggle with their logic and just have a better day if I don't engage. But I do seem to get notifications most of the time from muted accounts anyway.
In short I don't know, but I'm always happy to engage with relevant posts that are worded in a way that helps conversation flow!
