It is interesting to me how we use ',' (or '.' in some places in the world) for large numbers but we do not do that for small numbers.  For example we write "there are 100,000,000 satoshis in one BTC".  The ','s make it easy to read but we write "one satoshi is 0.00000001 BTC".  I wonder why we don't write "one satoshi is 0.000,000,01 BTC"?  That would help but I just have never seen it done.
