I still dont post anything- but have, as of late, started to reply/interact with some of those i follow if the topic is interesting.
I mainly do this for just another perspective, thought/idea on particular topic or news story etc.
Id love to talk about insurance, but that is such a hot-button topic that can really dredge up some emotional and angry replies, i tend to let those go by. Plus we have a very strict SM policy where i work, so instead of having to tread carefully, i simply dont tread lol
