Tumblr is a great service for creating, maintaining and publishing a tumblelog. Not everyone, however, is interested in just posting quotations, chats, and other bits, some still prefer to use tumblr for their full-featured blog. (And I most definitely think that tumblr is the better WordPress.)
If you have any questions, do not hesitate to ask!
