Not when politicians do it, perhaps, when you are at the receiving end, but in most other situations, I would say. Good because people don't necessarily know as much about your situation as you think. To me, I am the greatest thing that happened to the planet (!), but to others, I may be just a speck of dust. I am exaggerating, to make a point.
On social media, where scrolling is the norm, and attention spans are even less than in a classroom (contradictory as it may sound), explaining a post/picture is probably better than a cryptic caption that does not say much, and assumes that people know the context of what you are talking about- could be a new job, a change of place you live in, a new relationship, or multiple other things.
So here is some (unsolicited) advice- communicate, communicate, communicate. You may find the results are pleasant when you do.
