Therefore, the premise that you like baseball and I like baseball, so we should just hang out, will feel kind of pointless. That's why I don't think anyone has really nailed this market.
I think a better take on this would be, you want to publish a comic book, and I want to publish a comic book, so we should work on our projects and hang out. Or you want to run a 5K and I want to run a 5K so lets meetup and practice this together.
