Different Wikipedia pages have different purposes altogether. If it’s a page on science or technology than the possible reasons are that it’s there so that people can get information regarding something that is new. People think of making pages on many things but I’ve hardly met anyone who wanted to know how to create a Wikipedia page for a musician. Now, there must be thousands of people out there who want to know about how to do that but it’s just that I haven’t met any. So, I can only think of one reason why a musician would want a Wikipedia page and that’s most probably to engage their audience. Can there be other reasons for musicians having Wikipedia pages?
