I agree with this. But, that’s ok. Responsive Web Design is REALLY NEW and NOBODY knows how to do it properly/right/appropriately yet! We’re all just experimenting. And THAT’S FINE!
If the approach is deemed to be appropriate, then there is no reason why it can’t be done. If people do it on their own blogs, because they want to experiment, then that’s fine. It really is.
We’re all just trying to work this out.
