Same reason as Battera. When you read over your own article, you could also see another article, and you could like the Moc, and become a fan of the person. Just a way to get fans.

For catagory pictures, I would theroize that if people look at the catagoies you have,k and notice the pictures, they might like the look of it, and check out the page.

So, yeah. Both may be for ego reasons, but it's still something to have.
