I think our collections have a lot of overlap, bonus points for Wishlist to!
I often look at others collections when responding to posts. I do find people with similar pins easier to get along with, often the same perspective on things!
Club threads are the best for this, plus you often see the same Pinsiders across multiple club threads with similar tastes in pinballs. Plus it also helps to see the trolls that just post in everything!! Do they even play pinball?
