Posterous locks you into one template and one format, but the simplicity and ease of posting makes it an interesting option for student blogging. The Posterous bookmarklet tool could be handy for having students blog about current events stories. To do this have students find and read an article online, click the Posterous bookmarklet, when the dialogue box opens they can then write a response to the article and post it directly to their Posterous blogs.
