You are definitely right!

The day I got my account approved, I was told to browse the "introduceyourself" tag to know how to create my introductory post too.
I became confuse because most of the post I saw wasn't really about introduction. They were more of selfies and normal posts.

The tag has really been abused. In fact, most of the trending post on the tag aren't made by newbies. They are posts from members with good reputation.
