Does A Domain Name Have To Reflect A Niche?

I remember years ago someone said to come up with a domain name people will remember. And, at that time I came up with some truly goofy names. Surprisingly people came . . . They even clicked my affiliate links and purchased something.

Then, I joined WA and learned about niches and how a domain name and niche "should" go together . . . Well . . . I have a throw-back goofy domain name that corresponds with a niche I have absolutely no interest in pursuing . . . (It's hosted right here at WA) . . . But I like the name and don't want to give it up. Plus my affiliates are associated with it.

Over the years this particular website has become a collective kitchen junk drawer. I get traffic, I get sales. It's adding valuable content that's an issue for me. My other niche websites are a no-brainer for me in adding relevant content. This one, I love it . . . but I'm having trouble adding content as I said before . . . My other websites are in areas of interest to me and I don't want to use similar content to this particular website.

I think maybe I've outgrown the kitchen "junk drawer" concept. Perhaps I need to find another niche . . . Any suggestions would be greatly appreciated.
