nanolimits - a waste of time?

[bubbahotep]

I've seen people say that .01/.02, .02/.04, etc are a waste of time.

It seems to me if you can't make money there, (where players should be weaker) you shouldn't be able to make money at any higher limits (where players are generally better).

What is the popular belief on this?

If nanolimits really are a waste of time, what is the rationale for this belief?

Thanks
