What are best practices for a bookmarklet?

I'm creating a social sharing bookmarklet and button that lets users share a link along with an optional text.

What structure is more recommended to use?

this:

http://www.example.com/?share=http://www.example.net&text=hello

or with a folder:

http://www.example.com/share/?url=http://www.example.net&text=hello

(Or a completely different one?)
