It's an interesting behavior though, not just Chrome, but everyone. Certain numbers have meanings (1.0 being the most famous), just like extra tags like "alpha" and "beta". They're a signal to IT folk to measure progress, and at least the perceived value of an upgrade (1.0 to 1.1 is a small change compared to 1.0 to 2.0). There's also expectations of compatibility. Files made with 1.0 should work with 1.1, but 2.0 might have breaking features that need to be looked into deeper. Of course this varies with every single piece of software. You're right that for Chrome, it doesn't matter nearly as much, because updates are automatic. I just find it very interesting to see some software shoot up quick (maybe a 1.0 after 6 months), and then other software takes a lot longer (vlc taking years and years to hit 1.0).
