As {{Information}} will be one of the primary sources of image metadata for years to come, I thought it important to find all images that I, personally, uploaded to Commons that lack said template.
So I wrote Yet Another Tool. Turns out, over 48% of my images lack that template! Well, I've been uploading to Commons since forever, that is, before {{Information}} existed. So much for rationalization...
But, check yourself! Of Brianna's uploads, less than 9% lack {{Information}}. Yay! http://tools.wikimedia.de/~magnus/mynoinfo.php?user=Pfctdayelise
Also, she has uploaded exactly 333 files now, and has to buy a round! ;-)
Cheers, Magnus
