Articles in a wiki are meant to be collaborative efforts, not written by a single person, but by a lot of them. On the other hand, blogs are meant to be written by a single person.

Also, given its status as unofficial articles, they can have things that normally a wikia article cannot have, such as fanfiction or original work, personal stories, news articles, reviews...
