Badges how many?
How many badges are there?
why are they so hard to get?
There are many, many badges out there! Just participate a lot and don't worry about them! There are some that are really easy (like your first edit) and some that are a bit harder to earn, but if you just continue with the site, you'll earn some without realizing it.
Just looking down the current page Issabela has 618 badges. They can't be too hard to get. Just participate and they will accumulate.
