I wonder why 'self publishing' tools for kids always almost force them to produce ugly things. Is the assumption that they don't have any taste, or (which is almost the same) only like things that blingbling?
Then, on the other hand, why are publishing softwares for adults always soooo limited in features and why are for instance all blog lay-out templates that much restricted?
