Not too many people use the Service menu but there are some functions which are quite useful. I personally like the Summarize and Checksum services but most of them are useless.

In comes Service Scrubber to clean up the Service menu to make sure that you can get rid of all those useless services and give the menu a fresh look. Additionally it enables the user to make add keyboard shortcuts to services. The product is freeware, extremely simple to use, and can be downloaded here.
