I think one of the reasons we share our labels here, is an ice breaker. To see that at least here there are people who have things in common with ourselves and we can see this at a glance. Not to label ourselves but to share ourselves quickly. I guess I could just as easily share more but that is for my profile page if someone is interested in knowing more.

I can see at a glance that 2 other people take the same med I do and can ask those 2 people a question or I can see that many people take a particular med and not feel out of place.
