I don't know if anyone has seen this site
http://www.eatmyhamster.com/
but the submit page is absolutely amazing!!
The form adjusts whether you want to submit a video, picture, story, etc.
Enter an URL and it grabs all the images from that page and you get to pick which one is associated with the story.
You can upload an image as well
For video it asks for the embed code.
Their bookmarklet takes the title and any selected text as well as the URL.
I also like how the embedded videos aren't displayed on the list pages, only on the specific "discuss" pages.
Very slick site, especially the submit page.
Good hunting ground for ideas for Pligg.
