@Gargron I use quote posts for curating: adding local context and making connections, in order to interest people to investigate ideas/articles that may not be obvious from the original poster's text. I'm a bumble-bee, I cross-pollinate and spread ideas into new fields :-)

With a quote, both my addition (as a pointer) and the original (the substance) are visible; but here, doing it inelegantly with Reply, the substance is hidden in the timeline :-\
