I Googled money for the first time before starting this blog.
Have you ever tried Googling Money? If not try it, you'll find many web pages with different explanations about money. I found only one page with the relevant information, rest are out of scope for me. The only relevant page was of Wiki, the website one can trust on. But I was looking for a short information about Money, and reading Wiki page for just the definition of Money is not advisable.
Now, I tried again and Googled "define:Money", this is the way to find out the definitions of a word available on the net or say internet. This time I got a nice definition of Money which states that
"Money is the most common medium of exchange."
Euro is widely used currency in almost all the European countries. $ is widely accepted currency all over the world. But Money remains same, whatever one call it. It will still remains the rectangular piece or coins.
