Dear Dr Guitar

As I am not Ebbie, Dr Gutiar and so on I was not sure if I was allowed to look at THAT site - so I did.

It talks about 'a run of F chords'. I am familiar with 'runs on the dollar' and this site, for example, says that a serious run on the dollar could have severe impact on the American Economy.

I am concerned that a run on the F chord might do something similar musically. Can you reassure me?
