Yep. I like talking to other people, even just a little, and especially about biking. I've been known to yell out "nice bike!" when I see a sweet steel frame rolling by. The best thing anyone has ever told me was "That's a heavy bike to ride up this hill!" we chatted a little, and it felt awesome that Mr.Carbon Bike gave me props for riding an old hi-ten.
It probably makes a difference what kind of cycling you do too; I'm a commuter.
