I don't love the feature, although I do sometimes look through my friends' transactions. I guess it's similar to sharing a photo on Facebook, or doing a "check in" when you're at a location: it's simply about broadcasting who you were with and what you guys were either doing or bought. Most transactions between parties are simply "drinks", pizza emojis, or "rent" to a roommate. It's about showing who you are, what you do, and who you're with.
