Services is awesome, and there are a few other modules out there that make it even more awesome. The problem is that they are hard to find because of the generic nature of their names.
It would be a great help if, on the Services module page, we could list modules related to Services. It is almost impossible to find these types of modules by Googling
Drupal Services, because you end up with listings of Drupal shops, not modules related to Services.
I think it would be a great help to the community to list these, and any others like them, on the module page.
*Full Disclosure - Services Rules is mine. I think that it is worthy to be mentioned, but I'm not vying for self-promotion. I came across this difficulty of finding Services-related modules when working on a project. Between the default Services module, Services Views, and Services Rules, I feel that custom coding of services can be almost completely eliminated for most use cases. They are a powerful combination!
