We have an anniversary coming up and DP is jokingly "threatening" to put a gushing post on SM, as he knows I'd hate it, but several of our friends do do it.
He'll do something lovely privately, but IMO it is private and there's no need for online bragging. There's possibly also a part of me that feels it might be tempting fate!
If you do it, why do you like it and if you don't, why don't you like it?
