Oh nice one. I think both work just fine for me. It will be a lot more convenient if the person happened to know at least basic stuff about my interest; it will at least skip the “introducing” part.

I also don’t mind if they have opposite taste, just like you mentioned. The important thing to understand here is the willingness to know, learn, and understand. From my side, I don’t mind having to go further just to learn things I didn’t know before.
