I have two opposite routines from yours. Haha. One, I never zap something I don’t later comment on. I think in my mind, I don’t want to be one of those who just spots trending posts and zaps early in order to get sats. Not suggesting that you are an sats farmer though! I also think it I zap something and ask a question, I will usually benefit from the response the OP gives me, so that’s why I pair zapping + commenting.

Secondly, an idea floats in my mind. I mentally categorise under the most appropriate territory. And then I come to SN to write. In fact, these days I collect fun facts and book recommendations in preparation for subsequent weeks haha
