A blog that consists mostly of reviews of the media that the author watches/reads, or perhaps a review site constructed with blogging software. Particularly common are anime blogs (usually on an episode-by-episode basis) and book review blogs. These can build up a community of readers who share the writer's tastes - in the case of TV shows and anime fansubs, considerable discussions can arise in comment sections for the entries, acting almost like a discussion forum.

Anime and Manga

• Anime Nano is an aggregator of anime blogs, including those of some shameless self-promoting contributors.
• Animeblogger has a fair number of hosted anime blogs as well, and has its own aggregator.
• Anime Bites.

Literature

• Cinnamon Bunzuh is a blog that reviews the Animorphs series. It uses an hybrid synopsis/stream-of-thought discussion format, with the authors starting with a description and then going into a conversational play-by-play of sorts of the notable moments in a book. Found here:
• Mark Reads Harry Potter, is a popular blog that reviews each Harry Potter book, chapter by chapter. Mark is currently in Deathly Hallows. He likes the series a lot.
  • Before that, there was Mark Reads Twilight. He didn't like it very much.
  • And now he's doing more reviews- including The Hunger Games, Firefly, Doctor Who, and Avatar: The Last Airbender! Collectively his new sites are called Mark Does Stuff.
• Reasoning with Vampires is a blog dedicated to providing a line by line analysis of the Twilight series. This differs from most criticism of Twilight in that the blog focuses on grammar, rhetoric, and technical execution instead of plot. (though there is still plenty of criticism on plot)
• Stainless Steel Droppings does this for science fiction and fantasy books, movies of all genres and - increasingly - genre-related art and illustration.
• BloggerBeware is a blog that reviews (read: ingeniously mocks) every one of R.L. Stine's Goosebumps, Goosebumps 2000, and eventually, Horrorland books. Has its own main page on tvtropes.

Newspaper Comics
