M C Morgan about weblogs and wikis:
“Blogs and wikis, because they are different spaces, manifest/take advantage of/engage different epistemic and rhetorical possibilities and serve different rhetorical and epistemic ends. They engage different rhetorics: one topical, carved from the inside out; the other chronological, staying on top of things.
However, posting on a blog is easier than on a wiki in great part because you do not need to decide where to post: you post to the top, or in an already-defined category. On a wiki, one has to find a place to put the post, which costs cognative overhead.”
