I can understand why. I wouldn't call it a camera, though. I'd call it, "Outsourcing the metadata."
Metadata is geek-speak for the text information that's stored with every digital photo - mostly it's documenting date, exposure, location (if the camera has GPS), camera, and for some cameras, lens info - that's all done automatically. It also has room for captioning, if you fill it in. That's where this service comes in.
If you have decent captioning entered in your metadata it makes it easier for you to search your photo archive, and put it up online without having to re-enter the caption and description. Once a photo is online with captioning and descriptions, it's easy for the search engines to find it. If you want your photos discovered in a search, captioning and descriptive text is the way to do it - Google can't interpret images.
Programs like Adobe Lightroom and Apple Aperture allow you to semi-automate captioning/descriptive info, but still, when you have thousands of shots to catalog, it can get pretty tedious. If you're not a successful pro with eager interns willing to do the heavy lifting...
