I see that it's next to impossible to block format code snippets here. Argh.

Thanks for the great GM script. I have a "patch" for your review:

When scanning for the "description" url parameter to send to ma.gnolia, try checking for "notes" instead of "extended" - I'm not sure if they changed the tags or what, but this gets the description over to ma.gnolia successfully for me:

1) Added var declaration for "description":

var description = ""

2) Added case statment to look for "notes" node:

case 'notes':
description = childNode.innerHTML;
break;

3) Substituted "description" var for "extended" where URL string is built:

+ '&description=' + encodeURIComponent(description)
