Is it me or?

Okay well Is it me or are more new members are not making introductions. I know that I'm not the oldest member on here but wouldn't someone want to make an introduction to have people welcome them and introduce them to others? I thought that making an introduction to things was a must not to dive right in to the things. I mean I have seen new members who haven't made an introduction but yet they get their bums chewed out. Not meaning to sound like crabby pants.
