This I can agree with, it is very rare that I sit and think to myself, "That social media post was interesting" because usually, it's just something basic that either no one would be interested in, or it is something that probably should not be on the internet and social media.
I can understand the posts of selfies if you are achieving something or if you are doing something that is a lifelong goal, but a lot of the time, you see people just posting selfies with a caption just for the sake of it.
