Found an image on the web that doesn't have alt text, or just needs a good description?

http://objectdescription.org/

This seems kinda like a similar idea by WebVisum, where members of the WebVisum community can add "labels" to bad button/link text so the next WebVisum user gets a proper description.

Except here, it's anyone and everyone can add a description of an image.
How it works.

I like the idea, but wait til 4chan or whoever gets whiff of this.
