We very often forget that celebrities are just regular people with regular lives. I'm guilty of this. They sometimes just happen to be on our TVs or radios. It's a bit sad that we (as a society - not like you in particular) don't treat them that way. I can say with absolute certainty that there are a lot of celebrities who are here reading and posting all the time, without announcing who they are, with the same amount of chill. Rick and some others just happen to do so publicly without expecting much fanfare - just look at how many times /u/wil or /u/thisisbillgates have made posts/comments and nobody even noticed it was them.

Some are happy to do things like chat or sign autographs for fans, but in general, we just want to live ours lives as regular people without the constant attention that comes with celebrity status.
