So why donate to my blog when you can read all of the stuff for free?
A few donated coins (or dollars) will not make you broke nor will it make the musician rich.
It is simple a gesture of appreciation that you like their work and you wish to contribute a little coinage to help keep the musician (or food blogger) doing their craft.
FYI: Your tips will support the fun food content you will see on this blog. Give a little and get a lot.
