I remember reading somewhere that you should combine this (doing an activity) with wearing something that signals another interest. The idea is that you'll potentially find people where you already have 2 common interests. For example, going to this hackerspace with a concert t-shirt for one of your favourite bands. And lastly, if you want a deeper connection, you can't be afraid to be vulnerable.
There's no one-size-fits-all answer here. If you haven't already though, I would recommend you live together for some time first. Alone. Because you'll need to understand how to get along when you're with each other all the time.
