Responding to your question
editDear Dlivnat,
Don't worry, you didn't mess anything up: I was just making things a little clearer and simpler. I removed the "Sports" category because the category "Ultimate" is indirectly within it ("Ultimate" is categorized in "Frisbee" which in turn is in "Sports"). I was removing the redundancy, or "overcategorization" according to Wikimedia Commons guidelines (for your convenience, I produce the applicable text below). The short explanation is that "Ultimate" describes the images perfectly, while "Sports" is far too broad. Using only the specific category makes it much easier for someone searching for images to find what they are looking for. Hopefully, this makes sense.
From a practical standpoint, there are a number of categories that "require permanent diffusion", which means they are big, broad subjects (such as "dogs" or "cities") in which almost all images are better categorized more specifically (such as "Cocker Spaniel" or "Tel Aviv"). I patrol the "Sports" category periodically, and move images to each specific sport's category (you made it easy for me, all I had to do was remove the general category and I didn't have to search for a more specific one: thank you!).
Also, thank you for uploading these images. They are really quality pictures. Also, congratulations to Hebrew Wikipedia on 100,000 articles a month or two ago. Take care!

Over-categorization is what happens when an image is placed in several categories within the same tree. The general rule is always place an image in the most specific categories, and not in the levels above those. An example:
We'll assume that yellow spheres are spheres with a yellow color. We can think about Category:Yellow spheres and Category:Spheres. The picture to be categorized shows yellow marbles. We categorize the file in Category:Yellow spheres. Now, if we also categorize the image file in Category:Spheres, this is over-categorization: because we already know that the yellow marbles are spheres. This applies to most images: As mentioned above files in Category:Paris should not also be in Category:France, files in Category:Albert Einstein should not be in Category:Physicists from Germany and so on.
