I apologize to the blogger who shared Simple Spark . . . I can’t recall where I read about it, but I wanted to share it here.
The Simple Spark Catalog is the place to find all of the really cool web applications, or "apps" that will become an integral part of your life online.
Not only does the Simple Spark Catalog have a comprehensive listing of really cool apps that gets larger every day, but we also give you the tools to organize and share all these apps with your friends. Our catalog is a marketplace where both established companies and independent developers come to strut their stuff.
